Frequently Asked Questions
How many eggs does a chicken lay per year?
High-production breeds lay 280-320 eggs per year in their first year. Heritage breeds produce 150-200 eggs, and bantams lay 100-150. Production drops about 15% each year after the first.
Do chickens lay fewer eggs in winter?
Yes, production drops about 40% in winter due to shorter days. Hens need 14-16 hours of light for peak laying. Adding a coop light on a timer can maintain production through winter months.
How much feed does a laying hen eat per day?
A laying hen eats about 1/4 pound (4 oz) of feed daily, roughly 1.5 lbs per week. At typical feed prices, this costs about $0.06-$0.08 per hen per day.
At what age do hens start laying?
Most hens begin laying at 18-22 weeks old. High-production breeds start earliest, while heritage and bantam breeds may wait until 24-28 weeks. First eggs are often small and become regular over a few weeks.
How long do chickens keep laying eggs?
Hens lay productively for 2-3 years. After the first year, production declines about 15% annually. Most hens still lay occasionally for 5-7 years but at much lower rates.
Is it cheaper to raise chickens for eggs?
Feed costs work out to roughly $1.50-$2.50 per dozen eggs, compared to $3-$6 at the store. Once you recover startup costs (coop, feeders, chicks), backyard eggs save money and are fresher.
