Free-range farming grants chickens the freedom to roam, forage, and behave naturally — but that freedom only works if the birds have a secure, well-designed home base to return to. The coop is not optional. It is the hub of the entire operation: the place where birds sleep safely, hens lay eggs reliably, chicks grow without stress, and your labor efficiency either thrives or suffers depending on how thoughtfully the structure was designed.
This guide goes beyond the basic specs listed in general farming articles. It walks you through the actual build decisions: coop type selection, structural design for Philippine weather conditions including typhoons, PNS/BAFS-compliant space standards, complete nesting and perch specifications, brooder design, litter management, and a 2026 material cost breakdown — everything you need to build right the first time.

1 The Golden Rule: Why Housing Design Determines Farm Profitability
Most new farmers think feed is the most important variable in a free-range chicken farm. Feed is important — but a poorly designed coop will undermine even the best nutrition program. Here is why housing is the true foundation of profitability:
- Disease prevention: Overcrowded, poorly ventilated coops are the primary breeding ground for respiratory disease — the most costly and frequent health problem in Philippine free-range flocks. Every ₱1 spent on proper ventilation design saves ₱3–8 in treatment costs.
- Egg hygiene and quality: A coop without adequate, properly positioned nesting boxes produces floor-laid eggs — dirty, cracked, and unmarketable at premium prices. Premium buyers (hotels, supermarkets) reject floor eggs on sight.
- Predator losses: A coop with structural gaps, weak fencing, or no overhead netting can lose 5–20% of a flock to hawks, snakes, and dogs in a single night. These losses are entirely preventable with correct construction.
- Labor efficiency: A well-designed coop layout — with feeders, drinkers, nesting boxes, and litter management systems positioned thoughtfully — reduces daily farm labor by 30–40% compared to poorly designed structures. Over a year, this difference is significant.
2 Choosing Your Coop Type: Four Designs for Philippine Conditions
Philippine free-range farms use four main coop configurations. Each has specific advantages depending on flock size, capital, and management style. Choose based on your starting budget and 5-year expansion plan — not just immediate cost.
Ground-Level Open Coop
A simple open-sided structure with concrete or compacted earth floor covered by deep litter. Low build cost. Requires strict litter management to control moisture and ammonia. Highest predator risk at ground level — must have secure perimeter and overhead netting. Recommended for beginners starting with bamboo before upgrading.
Elevated / Slatted Coop
Floor raised 0.5–1.0m above ground on posts. Manure falls through slatted floor and is collected below — significantly reducing ammonia buildup and mite refuges in litter. Better airflow than ground-level designs. Birds access via ramp. Higher construction cost but dramatically reduces disease and parasite pressure. Preferred design in lowland and delta areas prone to flooding.
Hanging Coop (Suspended Cage)
Wire mesh suspended from overhead frame, with manure falling clear of birds. Excellent for high-value breeding stock where hygiene is paramount. Not suitable for large free-range flocks due to space requirements and cost. Often combined with a ground-level outdoor run accessible by ramp — birds spend the day ranging and nights in the elevated cage.
Portable / Movable Coop (Tractor)
A wheeled or skid-mounted coop that can be relocated every 1–2 weeks to fresh pasture. Breaks the parasite lifecycle in soil, maximizes forage value, and eliminates muddy patches in the run. Most effective for flocks of 50–100 birds on properties with sufficient land for rotation. Higher initial labor but minimal litter costs.
3 PNS/BAFS Space Standards: Legal Minimums and Recommended Targets
The Philippine National Standard (PNS) developed by the Bureau of Agriculture and Fisheries Standards (BAFS) defines minimum space requirements for cage-free chicken production. These are legal minimums — not recommended targets. For genuinely healthy, high-productivity free-range flocks, build to the recommended figures, which give birds more space and your farm more margin for growth.
| Space Type | PNS Minimum | Recommended for Free-Range | Notes |
|---|---|---|---|
| Indoor (single-tier coop) | 0.14 m² per bird | 0.18–0.20 m² per bird | = 5–7 birds per sq.m. For 100 birds: at least 18–20 sq.m. of usable interior space |
| Indoor (multi-tier / slatted) | 0.10 m² per bird | 0.12 m² per bird | Higher density acceptable only with excellent ventilation; not recommended for beginners |
| Outdoor run / range area | 0.5 m² per bird (2 birds/m²) | 1.0 m² per bird minimum | PNS minimum is tight — free-range premium pricing requires genuine ranging space |
| Brooder pen | 1 m² per 50 chicks (Day 1–30) | 1 m² per 30–40 chicks | Allow more space as chicks grow; expand brooder boundary weekly |
| Nesting boxes | 1 box per 3 hens; or 1 m² group nest per 120 hens | 1 box per 3 hens (individual) | Individual boxes preferred for egg cleanliness and monitoring |
| Perch space | 15 cm linear per bird | 20–25 cm per bird | More perch space reduces pecking order stress and comb injuries |
4 Structural Design: Orientation, Ventilation, and Roofing
Coop Orientation: Why East-West Is Non-Negotiable
Position the long axis of your coop on an east-west orientation. This single design decision delivers two critical benefits simultaneously:
- Birds inside receive early morning sunlight on the open side faces — sunlight provides Vitamin D synthesis and acts as a natural surface disinfectant
- The long sides face north and south — meaning the roof overhang shades the interior from the intense midday and afternoon sun that tracks north-south in the Philippines, preventing heat buildup inside
A north-south orientation does the opposite: the long open walls face direct east and west sun during the hottest parts of the day, creating a solar oven effect inside. This orientation mistake alone can raise coop interior temperatures by 6–10°C in Philippine summer months.
Ventilation Design
Heat stress is the silent productivity killer in Philippine free-range flocks. A hen that is chronically heat-stressed produces fewer eggs, lower-quality shells, and suppressed immunity — none of which show up as obvious disease but all of which show up as reduced income. Build ventilation into the structure from the start:
- Wall openings: Open-sided bamboo slat or wire mesh walls along the long (north and south) sides, from knee height upward. Allow at least 50–60% of the wall area as open mesh or slatted — not solid wall. Cover with fine-gauge galvanized wire to exclude wild birds and rodents.
- Semi-monitor or ridge-vent roofing: The roof design most effective for Philippine conditions is a split-type or semi-monitor design — the roof ridge has a raised vent section that allows hot air to escape from the top of the coop continuously. This chimney effect pulls fresh air in through the lower wall openings and exhausts hot, ammonia-laden air through the top.
- Coop elevation: Raise the coop floor 0.5–1.0m off the ground on posts. This improves underfloor airflow significantly, especially important for deep litter systems where decomposing manure produces heat and ammonia.
- Coop height: Build to a minimum interior height of 2.5–3.0 meters at the ridge. Low ceilings trap heat. A high ceiling creates the air column that allows convective ventilation to work.
- Night curtains (telon): Install rollable sack curtains or tarpaulin panels on the open sides. During the rainy season, typhoons, or cold nights, roll these down to protect birds from rain and drafts. Roll them up during the day for maximum airflow.
Roofing Materials
| Roofing Material | Heat Insulation | Durability | Cost (2026) | Verdict |
|---|---|---|---|---|
| Galvanized iron (GI) sheet | Poor — radiates heat directly | Excellent — 20+ years | ₱350–500/sheet | Most common; must have high ceiling and ridge vent to offset heat radiation |
| Pre-painted / color-coated steel | Better than plain GI — lighter colors reflect more heat | Excellent — 20+ years | ₱450–650/sheet | Best long-term option; white or light gray reduces heat load by 15–20% |
| Cogon grass / nipa | Excellent natural insulator | Poor — 3–5 years; fire risk | ₱50–150/bundle | Best heat control but requires frequent replacement; not suitable for long-term farms |
| Fiber cement board | Good | Good — 10–15 years | ₱280–400/sheet | Decent mid-range option; heavier than GI, requires stronger framing |
5 Nesting Box Design: Specifications, Placement, and Training Hens
Properly designed nesting boxes are the single most important factor for egg quality, cleanliness, and collection efficiency. A hen that lays in a nest box produces a clean, whole egg that goes directly to market. A hen that lays on the floor produces a dirty, often cracked egg that must be washed (reducing shelf life), may be stepped on (total loss), or may be contaminated with manure bacteria.
Individual Nest Box Specifications (PNS Standard)
Minimum per PNS/BAFS standard. Build slightly larger (40×35×35 cm) for dual-purpose breeds like RIR and Australorp which are larger-bodied than hybrid layers.
For 60 laying hens: 20 nest boxes minimum. Fewer boxes causes queuing, stress, and floor-laying by birds that cannot wait. More boxes are always better than fewer.
Mount nest boxes off the ground at hen chest height. Too low and birds soil them with litter. Too high and heavy breeds avoid them. Install a small perch bar below the entrance for easy boarding.
Nest box curtains (dark cloth or tarpaulin strips) give hens the privacy they need to lay calmly. Hens instinctively prefer enclosed, dark spaces — a curtainless box is less attractive and increases floor-laying.
Nest Box Placement Rules
- Position nest boxes in the coolest, shadiest part of the coop — north-facing walls for most Philippine orientations. Hens avoid hot nesting areas, especially during summer months.
- Never mount nest boxes above perches — hens roosting on perches will defecate into nests below, contaminating eggs before they are laid.
- Nest boxes must be draught-free — position away from the open-sided wall sections. Cold air directly on nests discourages use during the rainy season.
- Bank nest boxes in rows of 4–6 with a shared collection shelf behind — this allows you to collect eggs without entering the coop, reducing disturbance to laying hens.
Training Hens to Use Nest Boxes
Even perfectly designed nest boxes are sometimes ignored if hens were not trained to use them as pullets. The three-step training method:
- Install dummy eggs (plastic or hard-boiled eggs, or golf balls) in each nest box 2–3 weeks before expected first lay (around 16–18 weeks of age for hybrid layers). Hens instinctively investigate "eggs already present" and return to lay in the same spot.
- Restrict floor access in the early morning: Hens lay between 6–10 AM in most breeds. During this window, ensure birds cannot settle on the floor in their preferred spots — gently herd any bird attempting to squat on the floor toward the nest boxes for the first 1–2 weeks.
- Collect eggs at least twice daily — morning (after peak lay time, around 10–11 AM) and afternoon. Leaving eggs in the nest too long encourages broodiness and reduces the available spaces for other hens queuing to lay.
6 Roosting Perch Design: Specs, Materials, and Anti-Parasite Treatment
Perches serve two functions that directly affect farm profitability: they allow hens to express their natural roosting instinct (reducing stress and supporting welfare certification), and they elevate birds off the litter during the night — the period when red mites emerge from crevices to feed on roosting birds.
Perch Specifications
- Linear space per bird: 15 cm minimum (PNS), 20–25 cm recommended. For 60 hens: 9–15 meters total perch length
- Perch diameter / width: 3.5–5 cm (birds should be able to wrap toes around the perch and balance evenly without gripping hard). Flat-topped perches (rounded edges) are preferred over round dowels for large-bodied breeds — they reduce foot fatigue and bumblefoot risk
- Height above floor: 40 cm minimum from any surface; stagger perch heights by 15–20 cm if installing multiple levels to allow easy access from lower to higher perches
- Distance from wall: Minimum 20 cm from any wall — birds need wing clearance to mount and dismount
- Distance between perch rows: Minimum 30 cm — allows birds to move between perches without being obstructed by the bird on the perch above or behind
- Install timing: Introduce perches at around 35–45 days old — pullets need to learn to use perches before they develop laying and roosting patterns
Anti-Mite Treatment for Perches
Red mites (Dermanyssus gallinae) hide in cracks and crevices in wooden and bamboo perches during the day and emerge at night to feed on roosting birds. Heavy infestations cause anemia, reduced egg production, and extreme stress. Prevention is simple and costs almost nothing:
- Coat all wooden or bamboo perch surfaces — especially joints, crevices, and the underside — with used motor oil every 3 months. The oil blocks mite access points without harming birds
- Apply during the morning when birds are outside ranging — allow the oil to dry/absorb before birds return to roost in the evening
- Alternatively, perches made from smooth galvanized pipe (25–40 mm diameter) are naturally mite-resistant — no crevices for mites to hide in and smooth surface is easy to wipe down
7 Litter and Flooring: The Deep Litter System Explained
The deep litter system is the most practical flooring management approach for Philippine free-range coops. Done correctly, it creates a living microbial layer that actively composts manure, suppresses ammonia, controls pathogens, and provides a warm, comfortable substrate for birds — all at minimal cost.
How the Deep Litter System Works
Rather than removing manure daily, you add fresh litter material on top of existing litter periodically, allowing beneficial microorganisms to decompose manure continuously. The key is maintaining the correct moisture level — not too wet (ammonia, pathogens), not too dry (dust, respiratory irritation).
Recommended Litter Materials
| Material | Local Name | Availability | Pros | Cons |
|---|---|---|---|---|
| Rice hull | Ipa | Abundant nationwide; often free near rice mills | Excellent moisture absorption; good insulation for chicks; cheap | Can become compacted and anaerobic if wet — must be turned regularly |
| Carbonized rice hull | Ipa uling | Available; moderate cost | Superior moisture control; alkaline pH controls pathogens and mites; excellent for brooder | Slightly higher cost than plain rice hull; can be dusty if too fine |
| Wood shavings / sawdust | Kusot | Available near sawmills; varies by region | High absorbency; pleasant smell; easy to source in forested regions | Can mold if moisture-contaminated; avoid treated or painted wood waste |
| Chopped dried straw | Dayami | Abundant in grain-farming areas | Allows natural scratching behavior; good insulation | Compacts rapidly; needs more frequent turning than rice hull |
| Coarse sand | Buhangin | Available from river or construction supply | Does not compact; zero mold risk; easy to clean | Poor insulation for chicks; heavier; does not support deep litter biology as well |
Litter Management Protocol
- Starting depth: 8–10 cm at coop setup
- Add fresh litter: Every 2–3 weeks or when litter surface feels damp or compacted — add 3–5 cm of fresh material on top
- Turn the litter: Once a week with a rake or fork — this aerates the microbial layer and prevents anaerobic zones that produce ammonia
- Odor control booster: Dissolve earthworm castings (vermicast) in water with muscovado sugar and rice bran, ferment for 24 hours, then spray over coop litter. This multiplies the beneficial microorganisms that neutralize ammonia naturally
- Full litter change: Every 45 days minimum, or whenever litter becomes wet and cannot be corrected by turning and fresh addition. Full changes are also recommended at the end of each production cycle before new stock arrives
- Litter depth in brooder: 5–6 cm of rice hull or carbonized rice hull — deeper than this traps chicks; shallower provides inadequate insulation
8 Brooder Design: Getting Chicks Through the First 30 Days
The brooding stage — Day 1 to Day 30 — has the highest mortality risk of any stage in the chicken lifecycle. Chicks cannot regulate their own body temperature and are highly vulnerable to temperature fluctuations, drafts, and pathogens. A properly designed brooder eliminates these risks.
Brooder Space and Layout
- Space: Minimum 1 m² per 50 chicks (Day 1); expand the brooder ring weekly as chicks grow — Day 7: 1 m² per 40 chicks; Day 14: 1 m² per 25 chicks; Day 21+: allow free movement in a larger pen
- Shape: Use circular or rounded brooder rings (not square corners) — square corners allow chick pileups when chicks huddle for warmth, causing suffocation. A 1-meter diameter bamboo or cardboard ring works well for 50–80 chicks
- Litter: 5–6 cm of rice hull or carbonized rice hull — provides warmth and absorbs moisture from chick droppings
- Curtains: Hang sack curtains around the brooder ring and extend to the coop walls to retain heat inside the brooding area. This "tent" approach significantly reduces heating costs
Brooder Heating
| Age (Days) | Target Temperature | Lamp Height from Litter | Behavior Check |
|---|---|---|---|
| 1–7 | 31–34°C | ~60 cm (2 feet) | Chicks spread evenly under lamp — correct. Huddling under lamp = too cold. Spreading to edges = too hot. |
| 8–14 | 29–31°C | Raise lamp slightly | Continue monitoring spreading behavior daily |
| 15–21 | 26–29°C | Raise further | Chicks should be more active and less lamp-dependent |
| 22–30 | 22–26°C | Near ceiling height | Chicks feathering out and beginning to thermoregulate |
| 31+ | Ambient | Remove lamp | Full transition to grower pen — no supplemental heat needed in Philippine lowland conditions |
Waterers and Feeders in the Brooder
- Use chick-specific jar drinkers (not open troughs) — chick-sized openings prevent chicks from entering the water and drowning
- Place a single layer of marbles or pebbles in the drinker tray for the first 3 days — this prevents very young chicks from falling face-down in the water
- Position feeders and drinkers at chick back height — too high and chicks cannot reach; too low and they step in the water
- For Day 1–3: provide muscovado sugar water (10g sugar per liter of clean water) as the first drink — the quick energy source helps chicks recover from transport stress and stimulates drinking behavior
9 Typhoon and Monsoon Proofing: Building for Philippine Weather
The Philippines sits in the world's most typhoon-active region, with an average of 20 typhoons entering the Philippine Area of Responsibility annually. A free-range coop that is not designed for this reality is a business liability — one strong typhoon destroys an unanchored bamboo structure and kills or scatters the flock. This section is unique to Philippine farming guides and is not covered in most generic coop design resources.
Structural Typhoon Proofing Measures
- Foundation anchoring: Embed corner posts at least 60–75 cm into the ground. For GI pipe or concrete post structures, use a concrete footing (30×30 cm minimum) at each post base. Unanchored bamboo posts are the first thing to fail in strong winds.
- Cross-bracing: Install diagonal cross-braces (X-pattern or knee-brace pattern) on all four walls of the coop frame. This converts the structure from a rigid frame (which cracks) to a triangulated frame (which flexes and holds). Double the bracing on the windward side — in the Philippines, this is typically the side facing the Pacific (east) or northeast.
- Roof tie-down: Secure roofing sheets with J-bolts or tek screws with neoprene washers, not standard roofing nails. Standard nails pull out under typhoon uplift. Overlap sheets 2–3 corrugations minimum. Add purlins (horizontal roof support members) every 60 cm rather than 90 cm for typhoon-zone coops.
- Guy wires: For tall or long coops, install galvanized guy wires from the roof peak to ground anchor stakes on all four sides. These prevent the structure from racking (twisting off its foundation) in a typhoon.
- Rollable curtains: Ensure your night curtains (telon) can be fully lowered and secured before a typhoon. Sidewall curtains that allow wind inside the coop act like a sail — internal pressure can blow the roof off. Close all sides completely before a typhoon makes landfall.
Monsoon Season Management
- Ensure the outdoor run has drainage channels that direct rainwater away from the coop entrance. A coop built on a slight elevation (15–30 cm above the run level) prevents rainwater from flowing into the coop and wetting litter.
- Install a deep roof overhang of at least 60–90 cm on the windward side — this deflects driving rain from entering through the open wall sections.
- Have a stockpile of fresh dry litter (rice hull) ready before the rainy season. Wet litter is your biggest health challenge from June to October — the ability to immediately add fresh dry material over wet spots prevents ammonia spikes and respiratory outbreaks.
10 Lighting for Laying Hens: Natural and Supplemental Light Protocols
Chickens are photosensitive — egg production is directly controlled by the amount of light they receive each day. Understanding and managing light is one of the highest-return, lowest-cost interventions available to a free-range layer farmer.
How Light Controls Egg Production
Light entering the hen's eye stimulates the pineal gland to release reproductive hormones. The critical threshold is 14–16 hours of light per day for peak egg production. Below 12 hours, hens begin to reduce or stop laying — this is why free-range hens in the Philippines naturally slow down during the rainy season (June–September) when cloudy days reduce effective daylight.
PNS Minimum Light Requirements for Layers
- Minimum 8 hours continuous light per 24-hour cycle
- Minimum 6 hours continuous darkness per 24-hour cycle
- For peak production: 14–16 hours light per 24-hour cycle
Supplemental Lighting Protocol
For free-range operations that want consistent year-round production without seasonal dips:
- Install 1 bulb (11–15W LED) per 10–15 m² of coop area — bright enough to read a newspaper at bird level is the practical brightness test
- Add supplemental light in the evening (extend daylight artificially from dusk until target total hours are reached) — this is more practical and less disruptive to birds than pre-dawn lighting
- Use a timer switch to ensure consistent on/off timing — inconsistent light schedules stress hens and reduce rather than increase production
- Dim the lights gradually before switching off at night — abrupt darkness causes birds to panic and pile. Use a dimmer switch or switch off a portion of lights 15–30 minutes before full darkness
- Do not use artificial light for chicks or growers — supplemental lighting should only begin when pullets reach point-of-lay (16–18 weeks for hybrids, 5–6 months for native breeds)
11 Material Cost Comparison: Bamboo vs. GI Pipe vs. Hollow Block (2026)
Your choice of construction material is the most consequential long-term financial decision in coop building. The cheapest material upfront is almost always the most expensive material over a 10-year horizon when rebuilding costs are factored in. Here is an honest 2026 cost comparison for a 100-bird coop (approximately 20 m × 5 m = 100 m² floor area):
| Material Type | Build Cost (2026) | Expected Lifespan | 10-Year True Cost | Best For |
|---|---|---|---|---|
| Bamboo + nipa/cogon | ₱35,000–55,000 | 3–5 years | ₱70,000–165,000 (2–3 rebuilds) | Pilot/trial farms only; not recommended as permanent structure |
| Bamboo + GI sheet roof | ₱45,000–65,000 | 5–7 years (frame fails before roof) | ₱90,000–130,000 (1–2 rebuilds) | Starter farms with limited capital; upgrade frame to GI pipe by Year 5 |
| GI pipe frame + GI sheet roof | ₱70,000–100,000 | 15–20 years | ₱70,000–100,000 (no rebuild) | Recommended — best total value; termite-proof, typhoon-rated, no termite issue |
| Hollow block walls + GI frame + roof | ₱120,000–180,000 | 30+ years | ₱120,000–180,000 (generational investment) | Large commercial operations 500+ birds; overkill for starter 100-bird farms |
🎋 Bamboo / Indigenous Materials
- ✓ Lowest upfront cost
- ✓ Locally available in most provinces
- ✓ Easy to modify during construction
- ✓ Good thermal insulation
- ✗ Termite (anay) damage within 2–4 years
- ✗ Harbors red mites in bamboo joints
- ✗ Structural failure risk in typhoons
- ✗ Highest 10-year cost due to rebuilding
12 Step-by-Step: Building a 100-Bird Free-Range Coop
This sequence assumes a GI pipe frame + GI sheet roof structure, east-west orientation, elevated floor design, for a 100-bird flock (approximately 60 layers + 40 growers/broilers). Adjust dimensions proportionally for different flock sizes.
Clear a 12m (E-W) × 8m (N-S) footprint. The coop itself will be 10m × 5m; the remaining space is working area and future expansion buffer. Level the site and confirm drainage slope is away from the coop area. Mark corner post positions with stakes.
Dig 70cm deep holes at each corner and at 2m intervals along the long sides. Set GI pipe posts (2-inch schedule 40 minimum) vertically, checking plumb with a level. Pour concrete footing around each post (1:2:3 mix; minimum 25cm × 25cm × 30cm depth). Allow 3 days curing before proceeding.
Weld horizontal rails at 60cm and 120cm height along all four sides. Install diagonal knee-braces at every corner and at 4m intervals along the long sides. The wall frame should reach 2.5m height at the eave. Install typhoon guy-wire anchors at ground level on the windward side (east face).
Install roof purlins at 60cm spacing (typhoon standard). Frame a semi-monitor ridge vent — a raised center section 30–40cm above the main roof line, open on the long sides, that creates the convective vent effect. Cover the vent opening with fine wire mesh to exclude birds. Attach pre-painted GI sheets with tek screws and neoprene washers, 3-corrugation overlap minimum.
Cover the lower 60cm of the N and S walls with solid material (GI sheet or hollow block) as a kickboard to prevent rain splash-in. Above the kickboard: galvanized wire mesh (1-inch hexagonal) to ceiling height for ventilation. Install rollable tarpaulin curtains on the outside of the mesh for typhoon/rain protection. For elevated floor design: install slatted bamboo or wire mesh floor 50cm above ground level with a ramp on the south-facing side.
Mount 20 individual nesting boxes (35×35×35 cm minimum) in 4 rows of 5 on the north wall, 45–60cm above floor level. Install sack curtains on each box opening. Hang nest box perch bars 15cm below each box entrance. Install perch rails (GI pipe 35mm or smooth bamboo) at 40cm height, 25cm spacing, along the south and center walls. Apply used motor oil to all bamboo/wood perch surfaces.
Lay 8–10cm of carbonized rice hull across the coop floor. Install feeders (trough type with anti-waste lip) at bird chest height — 1 per 25 birds. Install nipple drinker lines or bell drinkers at beak height — 1 drinker per 15 birds. Install LED lighting at 1 bulb (13W) per 15 m² floor area, connected to a timer switch set for 14 hours light/10 hours dark.
Fence the outdoor run (10m × 10m minimum for 100 birds) with 6-foot bamboo or GI pipe posts and galvanized chicken wire, double-staked at corners. Install overhead hawk netting (fine polyethylene net) across the entire run area, supported by a center ridgeline wire. Install foot well containers at each access point with Zonrox solution.
