Chicken Feed Calculator
Calculate feed for your backyard chicken flock
Estimate how many pounds of chicken feed you need per day, week, month, or custom season. Add a waste buffer, bag size, and feed price to plan what to buy.
How to use the chicken feed calculator
Start with your flock size and the closest chicken type. The calculator uses common planning amounts for backyard flocks, then lets you adjust the pounds per bird per day if your feed label, breed, weather, or experience suggests a different number.
For adult laying hens, a practical starting point is about 1/4 pound of feed per chicken per day. Appetite can change with breed size, egg production, molt, heat, cold, free-ranging, treats, and feeder style.
Quick chicken feed planning examples
- 6 laying hens: about 45 lb per 30 days before waste, usually one 50 lb bag.
- 12 laying hens: about 90 lb per 30 days before waste, usually two 50 lb bags.
- 4 bantams: often around 18 lb per 30 days before waste.
FAQ
How much feed does one laying hen need each day?
Many adult laying hens eat around 0.24 to 0.28 pounds of feed per day. Use 0.25 lb as a simple planning number, then adjust if your flock consistently leaves feed or empties feeders early.
How long will a 50 lb bag of chicken feed last?
Divide 50 by your flock's daily feed use. Six hens eating 0.25 lb each use 1.5 lb per day before waste, so a 50 lb bag lasts about 33 days before adding any spill buffer.
Can free-ranging reduce the feed I need to buy?
Sometimes, but do not count on pasture replacing a complete ration. Free-ranging may reduce feed use slightly during good forage seasons, while winter, molt, and heavy laying can increase appetite.
