A healthy adult chicken typically eats about 4 ounces (¼ pound or 120 to 150 grams) of feed daily, though this amount shifts with age, breed, and whether the bird is kept for eggs or meat.
New backyard flock owners are often surprised by how little a single chicken actually consumes. Overfeeding is a common mistake that wastes money and attracts rodents. Knowing the accurate daily intake by the gram helps you buy the right bag size, budget correctly, and keep your flock healthy. A standard 20 kg (44 lb) bag of feed lasts roughly 4 to 6 weeks for a small group of 4 to 6 hens. Below is the breakdown per bird, plus how to adjust for chicks, broilers, and free-range adjustments.
The Daily Feed Intake For Every Type Of Chicken
The general industry benchmark is 4 ounces of feed per adult chicken per day, but a laying hen in full production needs a slightly different amount than a growing broiler. Here is the current daily consumption broken down by age and purpose.
| Chicken Type | Daily Feed Per Bird | Notes |
|---|---|---|
| Laying hen (adult) | 120–125 grams (4.2–4.4 oz) | Sustains steady egg production |
| Broiler (meat chicken) | 130+ grams (4.6+ oz) | Increases rapidly as they grow toward butcher weight |
| Chick (0–8 weeks) | 10–25 grams (0.35–0.9 oz) | Starts at roughly 1 oz/day |
| Pullet (8–20 weeks) | 60–100 grams (2.1–3.5 oz) | Steady increase toward adult ration |
| Free-range adult hen | May drop to 1.8 oz (51 g) from pasture | Forage makes up the difference; still offer 4 oz of feed |
| Large-breed rooster | 140–170 grams (5–6 oz) | Larger birds need a bigger portion |
The numbers above assume clean, nutritionally complete commercial feed is the main diet. If your flock free-ranges actively, they may eat less from the feeder, but the standard allowance of 4 ounces per adult bird remains the safest starting point to prevent nutritional gaps.
How Much Feed For A Flock?
Scaling the daily number to your whole flock is straightforward. For a typical backyard group of 6 hens, plan on roughly 700 to 800 grams (1.5 to 1.8 pounds) of feed per day. A flock of 10 adult chickens needs about 1.2 kg (2.6 lbs) daily. For 20 birds, plan on 2.4 kg (5.3 lbs) each day.

Feed Types And Protein Levels By Stage
Chickens need a different feed formulation at each life stage. Switching too early or too late can cause health issues or poor eggshell quality. The protein percentage and feeding rate change with age.
| Life Stage | Recommended Feed | Protein Level |
|---|---|---|
| 0–6 weeks (layer breed) | Starter feed | 20% protein |
| 7–16 weeks (layer breed) | Grower feed | 17–18% protein |
| 16 weeks + (layer breed) | Layer feed | 16–17% protein (higher calcium) |
| 0–2 weeks (broiler) | Broiler starter | Non-GMO, ~1 oz/day |
| 3–8/9 weeks (broiler) | Broiler grower | 18% protein |
Hens must be moved to layer feed at sexual maturity, around 16 weeks, because the added calcium supports strong eggshell development. Feeding layer crumbles or pellets too early can overload a young bird’s kidneys with calcium.
How To Feed Chickens Correctly
Getting the quantity right is only part of the job. The method matters just as much.
- Offer unlimited access. Chickens eat small amounts throughout the day, not in set meals. Keep a feeder available at all times with fresh feed.
- Check consumption daily. A sudden drop in how much they eat is often the first sign of stress, illness, or a batch of spoiled feed. A trough that stays full for two days is a warning.
- Keep feeders clean. Wash them regularly and remove any moldy or damp feed immediately. Moldy feed can sicken the entire flock.
- Manage free-range intake. If your hens run on pasture, natural foraging should make up no more than 20% of their total diet. Too much time eating bugs and greens can lead to obesity or nutritional imbalances.
- Ration only for weight control. Some owners give the day’s portion in the morning and ensure it is finished by dark. This reduces rodent attraction but must be done carefully so the birds get enough.
Common Feeding Mistakes
The most frequent error is assuming every chicken eats the same amount. A large breed like a Jersey Giant consumes more than a small bantam. Free-range hens that forage heavily may eat less from the feeder but still need the full ration available so they don’t fall short on calcium and protein. Another common mistake is storing feed in a damp area or leaving it on the ground — this invites mold and rodents. Always store feed in a rodent-safe container with a tight lid.
Daily Feed Checklist
Keep this quick reference near your feed bin. For a flock of 6 adult laying hens, you will need roughly 1.5 pounds of feed per day. A 20 kg bag (44 lbs) lasts about 4 to 6 weeks. Adjust upward for larger breeds and meat birds, and adjust slightly downward if your birds free-range on lush pasture. The most important habit is weighing or measuring the first few days so you know your flock’s normal — then a change in appetite becomes an early warning instead of a mystery.
FAQs
Do chickens eat less in hot weather?
Yes, chickens typically eat less during hot weather because their metabolism slows down to stay cool. Their water intake rises significantly, climbing to roughly 0.08 to 0.16 gallons per bird. Monitor body condition and consider offering feed during the cooler morning or evening hours.
Can I feed my chickens kitchen scraps instead of commercial feed?
Kitchen scraps such as leafy greens, fruits, and vegetables can supplement a commercial feed ration, but they should not replace it. Commercial feed is nutritionally balanced with the right protein and calcium levels. Treats and scraps should make up no more than 10% of the daily diet.
How long does a 50 lb bag of feed last for 10 chickens?
Ten adult chickens eating the standard 4 ounces per day each consume about 2.5 pounds of feed daily. A 50 lb bag therefore lasts roughly 20 days, which aligns with about three weeks. Buying in larger bags can reduce the cost per pound for bigger flocks.
Should I feed my chickens in the morning or evening?
Most backyard keepers feed in the morning so the birds have energy through the day. For flocks on a rationed feeding plan, give the day’s portion in the morning and ensure it is finished before dark. This helps keep rodents away from the coop at night.
What happens if I overfeed my chickens?
Overfeeding leads to wasted feed that rots on the ground or attracts rodents and pests. It can also cause obesity in the flock, which reduces egg production and shortens lifespan. Measuring the daily ration per bird is the best way to avoid this.
