Egg production

Modern crosses lay 92–96% at peak (weeks 25–30), ~85% average over the cycle. Feed intake 110–120 g/head/day; conversion ~1.3–1.5 kg feed per dozen eggs. Peak lasts 8–12 weeks, then ~0.5%/week decline. Keeping birds past 80 weeks is a margin decision (egg price vs feed), not a habit.
