1 Why Free-Range Birds Have Different Nutritional Needs
Free-range chickens are nutritionally unique compared to birds raised in conventional cage systems, and this changes how you feed them:
- They forage: Free-range birds supplement their commercial ration daily with grass, insects, worms, seeds, and whatever they find in the run. This means their actual nutrient intake on any given day is a combination of what you give them and what they find. Good foraging design can realistically reduce commercial feed costs by 20–35%.
- They exercise more: Higher activity levels mean slightly higher caloric requirements for maintenance — but this is offset by better muscle development, better feed conversion, and a premium product that justifies the longer, slower growth cycle.
- They grow slower: Free-range broilers reach market weight in 60–90 days vs. 23–28 days for conventional broilers on synthetic hormones and preventive antibiotics. This longer cycle demands consistent, stage-appropriate nutrition throughout — you cannot shortcut any phase.
- Their eggs are nutritionally superior: A diverse free-range diet produces eggs with lower cholesterol and saturated fat and significantly higher levels of omega-3 fatty acids, Vitamin A, and Vitamin E — the exact nutritional benefits your premium buyers are paying for. This means quality feeding is literally part of your marketing claim.
2 The 6 Nutritional Components Every Feed Must Contain
Whether you use commercial feed, a homemade mix, or a combination, every ration for free-range chickens must supply all six of these components. Deficiency in any one leads to poor growth, low production, disease vulnerability, or behavioral problems like feather pecking.
| Component | Function | Best Local Sources (Philippines) |
|---|---|---|
| Carbohydrates (Energy) | Primary energy source; powers movement, egg production, body temperature | Yellow corn (mais), cassava, gabi, ube, kamote, rice bran (darak), binlid |
| Protein | Muscle growth, feather development, egg white and yolk formation; most critical nutrient | Soybean meal, copra meal, fish meal, suso (ground snails), azolla, madre de agua, mongo seeds, mealworms |
| Fats (Lipids) | Fat-soluble vitamin absorption (A, D, E, K); energy density; yolk color | Copra meal, full-fat soybean, rice bran oil (found in D1 rice bran) |
| Vitamins | Immune function, bone development, egg quality, stress response | Malunggay (Vitamin A, C, K), yellow corn (provitamin A), green forages, commercial premix |
| Minerals | Bone and eggshell formation (Ca, P), nerve function (Na, K), blood (Fe) | Limestone (apog), crushed eggshells, oyster shells, crushed snails, salt (asin), carbonized rice hull |
| Water | Digestion, temperature regulation, egg formation (egg is ~74% water); deficiency drops production by 10–20% within hours | Clean potable tap water or deep well; must be changed twice daily |
3 Protein Requirements by Stage
Protein is the most expensive and most critical nutrient in any feed ration. Too little causes slow growth and poor egg production; too much is wasted as urea and raises feed cost with no benefit. Target these crude protein (CP) levels at each stage:
| Stage | Age | Target Crude Protein (%) | Why This Level |
|---|---|---|---|
| Chick / Brooding | Day 1–21 | 20–22% CP | Rapid tissue development; feather growth; immune system formation |
| Grower (Pullet) | 21 days–18 weeks | 16–18% CP | Skeletal frame growth; muscle laydown; lower than chick stage |
| Pre-Layer / Pre-Breeder | 16–19 weeks | 17–18% CP | Reproductive organ development before first egg; transitional phase |
| Layer (Peak) | 19 weeks–78 weeks | 16–17% CP | Egg protein formation; sustained daily production |
| Broiler Grower | Day 1–42 | 20–22% CP | Maximum muscle accretion during growth phase |
| Broiler Finisher | Day 43–harvest | 18–20% CP | Finishing phase; shift toward energy for fat deposition and weight gain |
4 Commercial Feed Schedule by Age (2026)
Use this corrected and consolidated schedule. Previous versions of this guide had conflicting age ranges for broiler finisher — that has been resolved below:
| Age | Stage | Feed Type | Key Nutrient Focus |
|---|---|---|---|
| Day 1–21 | Brooding / Chick | Chick Booster or Chick Mash | High protein (20–22% CP); easy-digest crumble or mash form |
| Day 22–49 | Early Grower | Chick Starter (Starter Mash) | 16–18% CP; begin integrating forage access at Day 30+ |
| Day 50–84 | Late Grower / Broiler Finish | Broiler Finisher OR yellow corn (mais) | 18–20% CP for meat birds; energy-dense for weight gain |
| Day 50–18 weeks | Layer Grower (Pullets) | Grower Crumble / Grower Mash | 16% CP; controlled energy to prevent fat pullets |
| 16–19 weeks | Pre-Layer | Pre-Layer Feed (transition) | Increase calcium gradually; reproductive organ conditioning |
| 19 weeks+ | Layer | Layer Mash / Layer Pellets | 16% CP; high calcium (3.5–4.5%); stimulate with 16-hr light cycle |
5 Exact Gram-Per-Bird Feeding Amounts
These are the recommended daily feed amounts per bird at each age. Use these as baselines — adjust ±10% based on forage availability, breed size, and weather conditions.
| Age / Week | Daily Feed Per Bird | Daily Water Per Bird | Notes |
|---|---|---|---|
| Week 1 (Day 1–7) | 15 g/bird | 30–50 ml | Add red sugar (10g/liter) to water on Day 1 only for energy boost on arrival |
| Week 2 (Day 8–14) | 20 g/bird | 50–80 ml | Monitor crop fill — all birds should have full crops at night |
| Week 3 (Day 15–21) | 25 g/bird | 80–100 ml | Transition from chick booster to starter begins end of this week |
| Week 4–5 | 30–35 g/bird | 100–130 ml | Forage introduction can begin; reduce commercial ration proportionally |
| Week 6 | 40 g/bird | 140 ml | Full outdoor run access now; foraging significantly supplements ration |
| Week 8 | 52 g/bird | 170 ml | FCR target: 2.0–2.5 (kg feed per kg gain) |
| Week 12 | 72 g/bird | 200 ml | — |
| Week 18 | 93 g/bird | 220 ml | Switch pullets to pre-layer feed at week 16 |
| Layer (19 wks+) | 122 g/hen/day | 250–280 ml | Total feed per hen for full laying cycle (to 78 wks): ~45 kg |

8 Local Foraging Plants That Cut Feed Bills
Strategic planting in your outdoor run can reduce commercial feed dependency by 20–35%. These plants thrive in Philippine conditions and provide documented nutritional value:
Highest protein of any locally grown supplement. Substitute for rice bran (darak) in layer rations. Grow in shallow water basins near the coop. Doubles as a mosquito control measure. Shown to increase hatchability in breeding flocks.
Fast-growing shade tree. Chop leaves and offer fresh or dry and add to ration. Also serves as a shade provider in the outdoor run — dual function. Plant 5–10% of run area with madre de agua.
High-quality grazing grass suited for Philippine climate. Chopped and mixed with pellets, it can reduce commercial feed consumption by up to 50% for growing birds. Grows back quickly after cutting.
Drought-tolerant leguminous shrub. One of the best protein forages for Philippine farms. Chop-and-carry or plant inside the run for direct browsing. Grows fast and produces year-round.
Exceptional feed booster. Rich in Vitamins A, C, and E; calcium; and antioxidants. Dry and grind leaves into meal (2–5% of ration) to improve egg yolk color and immune function. Every free-range farm should have malunggay trees.
Highly palatable grazing grass. Plant inside the run for continuous browsing. Use rotational grazing: divide run into 2–3 sections and rotate weekly to allow recovery and break the parasite lifecycle.
Ripe bananas are a prized energy and vitamin supplement. Use overripe or damaged bananas from the farm. Green banana leaves can also be offered as enrichment and light feed. Plant on the west side of the run for afternoon shade.
Fresh leafy greens enhance egg yolk color to a deep orange-yellow — a visible quality marker buyers notice. Hang a whole cabbage or bunch of kangkong from the coop ceiling at bird height; birds will peck at it, preventing boredom and feather pecking.
9 Protein Supplements from the Farm
These locally sourced, high-protein ingredients dramatically improve ration quality without the cost of commercial protein supplements:
| Source | Local Name | Protein % | How to Use |
|---|---|---|---|
| Freshwater snails | Suso | ~60% (dry) | Crush shells and flesh; mix into ration at 5–10%; also excellent calcium source |
| Mealworms / Superworms | Alupihan | 50–55% (dry) | Farm your own in a bin using rice bran and vegetable scraps; offer live or dried |
| Earthworms | Bulate | 60–70% (dry) | Harvest from vermicompost beds; chop and mix fresh or sun-dry for storage |
| Black soldier fly larvae | BSFL | 40–45% (fresh) | Increasingly popular in 2026; self-harvest larvae from organic waste bins; excellent natural dewormer effect |
| Filter cake (taho waste) | Okara / taho | ~35% (dry) | Sourced from tofu/taho producers; dry and add to grower ration; cheap or free |
| Fish scraps | Basura-isda | 55–65% (dry) | Dry, grind, and add to ration at 3–5%; strong smell so limit quantity; excellent for broilers |
10 Natural Herbal Health Supplements
Free-range farming's premium market position depends on antibiotic-free, chemical-free production. These natural supplements maintain flock health without compromising that claim:
| Herb / Plant | Function | How to Administer | Frequency |
|---|---|---|---|
| Garlic + Red Chili | Natural antimicrobial; boosts immunity; repels intestinal parasites | Crush 5–10 cloves + 2–3 chilies per liter of water; strain and add to drinkers | 2–3x per week |
| Oregano | Respiratory health; anti-inflammatory; natural antibiotic (carvacrol) | Steep a handful of crushed leaves in hot water; cool and add to drinking water | Weekly or when respiratory signs appear |
| Lemongrass (Tanglad) | Detoxification; digestive aid; natural deodorizer reduces ammonia in manure | Boil and add cooled tea to drinking water; or plant around coop perimeter | Weekly |
| Ipil-Ipil Leaves | Natural dewormer (mimosine compound); laxative cleanse | Dry and grind leaves; add 3–5% to feed as meal; do not exceed — high doses cause toxicity | Monthly deworming routine |
| OHM (Oriental Herbal Mix) | Broad-spectrum health tonic; antioxidant; stress reduction | Ferment garlic, onion, ginger, and chili for 7 days; dilute 1:100 in drinking water | Every other day |
| Molasses | Energy supplement; rich in B vitamins, potassium, iron; reduces stress | Add 1–2 tablespoons per liter of water; or mix into feed at 1–2% | During stress periods (transport, vaccination, hot weather) |
| Papaya Leaves | Digestive enzyme (papain); natural anthelmintic (dewormer) | Dry, grind, and add to feed at 2–3%; or hang fresh leaves for birds to peck | Monthly or as needed |
11 Water Management
Water is the most underrated nutrient in poultry farming. A layer hen's egg is approximately 74% water. Even mild dehydration (5–10%) can reduce egg production by 10–20% within 24 hours — a loss that takes 2–3 days to recover from.
- Source: Use potable water only — if it is safe for human consumption, it is safe for chickens. Deep well, spring, or water district connection. Never use stagnant or irrigation water.
- Frequency: Change water twice daily — morning and afternoon. Do not let birds drink from 12-hour-old water, especially during hot Philippine summers when bacterial growth accelerates rapidly.
- Volume guide: A laying hen needs 250–280 ml of water per day under normal conditions; during the dry season (March–May), this can reach 350–400 ml. Always provide slightly more than estimated need.
- Drinker design: Use bell drinkers or nipple drinkers to prevent birds from entering the water container. If using open basins, add a metal grill or screen on top so only the beak, not the whole head, can access the water.
- Supplementation: During the first 24 hours after chick arrival, add 10 g of red sugar per liter of water to provide quick energy. After vaccination days, add a vitamin-electrolyte sachet to the water for 48 hours to reduce vaccine stress.
12 Seasonal Feeding Adjustments
Dry Season / Summer (March–May): Managing Heat Stress
Heat stress is the #1 production killer during the Philippine dry season. A hen at 35°C eats up to 25% less feed than at 25°C — directly cutting egg production. Counteract with these adjustments:
- Feed during the coolest parts of the day — before 8 AM and after 4 PM — when birds are most willing to eat
- Switch to higher energy-density feeds (more corn, more fat) so birds get maximum calories from smaller feed volumes
- Increase water availability — double the number of drinkers; add electrolytes (salt + sugar or commercial electrolyte powder) 2–3 times per week
- Add Vitamin C (ascorbic acid) to water at 200 mg/liter during peak heat; Vitamin C reduces heat stress hormones in chickens
- Provide extra shade in the foraging area; move drinkers into shaded spots
Rainy / Cold Season (November–February): Managing Wet Feed and Chills
- Keep all feed in waterproof containers or elevated off the ground — wet feed molds within hours and can cause fatal aspergillosis
- If feed accidentally gets wet, remove and discard it immediately — do not try to dry and reuse it
- Provide slightly more feed per bird during cold nights — birds burn more calories maintaining body temperature
- For chicks, use the fireless brooding technique: pack rice hull litter at 10–15 cm depth. Fermenting rice hull generates gentle warmth. Enclose the brooder tightly with sacks during cold nights. This works as a power-outage backup for the brooder lamp.
- Add garlic extract to evening drinking water to help chicks maintain warmth — not a scientifically proven effect, but widely used by Filipino farmers with positive results
13 Diagnosing and Fixing Common Nutrition Problems
🥚 Thin or Soft-Shelled Eggs
- Cause: Calcium deficiency; phosphorus imbalance; Vitamin D3 deficiency
- Fix: Add crushed eggshells or oyster shells as a free-choice supplement in a separate small feeder
- Fix: Ensure birds get sunlight for Vitamin D3 synthesis — minimum 4 hours direct sun per day
- Fix: Check that layer mash contains 3.5–4.5% calcium; switch brands if not
🐔 Slow Weight Gain in Meat Birds
- Cause: Protein deficiency; disease burden; overcrowding stress; poor FCR
- Fix: Verify protein % of current ration matches stage targets (Section 3)
- Fix: Add azolla, mealworms, or suso to boost dietary protein at low cost
- Fix: Check for worm burden — deworm with ipil-ipil if not done in past 2 months
🪶 Feather Pecking / Cannibalism
- Cause: Protein deficiency (especially methionine); overcrowding; boredom; lack of enrichment
- Fix: Increase dietary protein to 18–20%; add fish meal or mealworms to boost methionine
- Fix: Hang cabbage, kangkong, or a corn cob in the coop at bird-chest height — redirects pecking to food
- Fix: Ensure adequate foraging time (6–8 hours/day); bored birds peck each other
- Fix: As a last resort, dim coop lighting temporarily to reduce aggression
🌕 Pale Egg Yolks
- Cause: Low carotenoid intake; insufficient green forage; lack of yellow corn
- Fix: Increase yellow corn proportion in ration (primary carotenoid source)
- Fix: Add fresh malunggay leaves, kangkong, or dried marigold petals to feed — all are high in xanthophylls that deepen yolk color
- Fix: Ensure minimum 4 hours foraging daily on green pasture
📉 Sudden Drop in Egg Production
- Cause: Nutritional deficiency; disease; stress; inadequate lighting; feed change
- Fix: Check feed supply — was there a gap in feeding? Inconsistency causes production drops
- Fix: Verify lighting schedule provides 16 hours of light daily
- Fix: Rule out Newcastle Disease (ND) — sudden drops + neurological signs = call your vet immediately
💧 Diarrhea / Loose Droppings
- Cause: Dirty water; wet/moldy feed; intestinal parasites; bacterial infection; sudden feed change
- Fix: Change water twice daily without fail; clean drinkers daily
- Fix: Add garlic-ginger OHM solution to water for 3 days
- Fix: Transition feed changes over 5–7 days gradually — never switch feed abruptly
- Fix: If persists beyond 48 hours with mortality, consult a vet
