Poultry Feed Calculator: How Much Feed Does Your Flock Need?
Last updated: April 2026
A laying hen eats about 0.25 lbs of feed per day (roughly 7.5 lbs/month). Meat birds eat double that at 0.5 lbs/day. For 6 layers, plan on one 50lb bag per month at about $15. Use our calculator below for exact numbers based on your flock.
Key Takeaways
- ✓Layers: 0.25 lbs/day • Meat birds: 0.5 lbs/day • Chicks: 0.1 lbs/day
- ✓Feed is 60-70% of ongoing chicken-keeping costs
- ✓Buying in bulk (50lb bags) saves 15-25% per pound
- ✓Winter consumption increases 10-15% for body heat
- ✓Free-ranging reduces feed needs by 10-30% in growing season
Understanding Feed Types and When to Use Them
Different life stages and purposes require different feed formulations. Chick starter (20-22% protein) fuels rapid growth in the first 8 weeks. Grower feed (14-16% protein) transitions pullets from 8-18 weeks. Layer feed (16-18% protein) with added calcium supports egg production in mature hens. Meat bird feed (20-24% protein) maximizes growth rate for broilers.
Bulk Buying Strategies That Save Money
Buying feed in 50lb bags rather than smaller quantities can save 15-25% per pound. Many feed stores offer additional discounts for purchasing by the pallet (40+ bags). Form buying co-ops with neighboring chicken keepers to access bulk pricing even with smaller flocks.
However, feed freshness matters. Never store more than 4-6 weeks of feed supply, as fats in the feed can go rancid and nutritional value degrades over time. Use sealed metal containers in a cool, dry location away from rodents.
Seasonal Feed Adjustments
In winter, chickens burn more calories maintaining body temperature. Plan for 10-15% more feed during cold months. In summer heat, chickens naturally eat less but need more water. Supplementing with frozen treats and electrolytes helps maintain intake during heat waves.
Free-ranging chickens supplement their diet with insects, greens, and seeds, which can reduce feed consumption by 10-30% during growing seasons. However, don't count on this for winter planning.
Feed Conversion Ratios Explained
Understanding feed conversion ratios (FCR) helps evaluate efficiency. For layers, the FCR is about 4:1 — meaning 4 lbs of feed produces 1 lb of eggs (roughly 1 dozen). For meat birds, modern broilers achieve an impressive 1.8:1 FCR, converting feed to meat very efficiently. Heritage meat breeds are less efficient at 3:1 to 4:1.
