Calculate laying percentage, daily egg yield, feed efficiency and profitability for your layer flock. Track performance against industry benchmarks.
500 hens, 425 eggs per day, 60kg feed daily, eggs sell at $6/dozen.
At 85% lay and 1.69kg feed per dozen, this flock is performing well. Feed efficiency of 1.7 is excellent — many commercial flocks average 1.9-2.1.
Laying % = (Number of eggs per day ÷ Number of hens) × 100. Example: 100 hens producing 85 eggs per day = 85% laying rate. Peak production should be 85-95%.
Peak (25-40 weeks): 85-95%. 40-60 weeks: 75-85%. 60-80 weeks: 65-75%. Annual average: 280-320 eggs per hen.
Standard layers: 110-130g per hen per day. Feed conversion: 1.8-2.2 kg feed per dozen eggs. Free-range hens may need 10-15% more feed.
Stress, disease, poor nutrition, insufficient light (14-16 hours needed), extreme heat, moulting, and age (declines after 60 weeks).
