How this calculation works and what it assumes
- Intake depends on breed, age, temperature and feed energy.
- Hot weather reduces intake; cold weather increases it.
- A 4 percent wastage allowance is included.
What changes intake
- Age: pullets eat less than hens in full lay.
- Temperature: hot houses cut intake; cold weather increases it.
- Feed energy: a denser ration means fewer grams for the same nutrition.
- Body size: heavier breeds eat more.
- Wastage: shallow, overfilled feeders lose feed to the litter every day.
Keeping feed cost under control
- Fill feeders no more than two thirds full.
- Raise feeders to the level of the birds' backs.
- Buy from a consistent, reputable source rather than switching for small savings.
- Track feed used per tray of eggs — that single number shows whether feed is working for you.

Common questions
How much feed do 100 layers eat per day?
At 120 g per bird, 100 layers eat about 12 kg a day, roughly 84 kg a week, or about seven 50 kg bags a month.
Should I restrict feed to save money?
Restricting feed in laying hens usually costs more in lost eggs than it saves in feed. Reduce wastage instead.
