How much does it cost to feed chickens per dozen eggs? This page keeps two numbers separate on purpose: feed-only cost per dozen and all-in cost per dozen. Mixing them is why different tools seem to contradict each other. It runs entirely in your browser and saves or sends nothing.
Feed per day = hens × lb per hen per day × (1 + waste). Eggs per day = hens × eggs per hen per week ÷ 7. Feed per dozen = feed per day ÷ (eggs per day ÷ 12). Feed cost per dozen = feed per dozen × price per lb. All-in cost per dozen = feed cost per dozen + (other monthly costs ÷ eggs per month × 12). Cost per egg = feed cost per dozen ÷ 12.
With the defaults above: 10 hens × 0.25 lb × 1.05 waste = 2.63 lb of feed per day. At 5 eggs per hen per week, that is about 7.14 eggs per day, so feed per dozen is about 4.41 lb. At $20 for a 50 lb bag ($0.40 per lb), feed cost is about $1.76 per dozen. With $10 of other monthly costs, all-in cost is about $2.32 per dozen. Change the bag price or lay rate and both numbers move — that is the point: neither number is a fixed price.
A University of Maryland Extension small-flock example gives 4.5 lb of feed per dozen and $3.37 per dozen all-in in that example, excluding labour. That $3.37 is an all-in example figure, not a feed-only figure and not a current price, so do not compare it directly with a feed-only result from this page. Seasonal lay rate matters too: the same flock costs more per dozen in winter when fewer eggs are laid, even if feed use stays the same.
Is this a profit promise? No. It only estimates cost from the numbers you enter; egg prices, losses, veterinary costs and your time are not fully covered, and labour is excluded from the all-in figure unless you add it to other costs yourself. What if lay rate changes? Enter the current rate, not the best week. Do I need an account? No. This page is not legal, financial or veterinary advice.
