Frequently asked questions
How many eggs does a hen lay?
Prolific breeds lay 5–6 eggs a week in season; averages are closer to 4–5, dropping with age, molt and short winter days.
Why did my hens stop laying?
Usually shorter daylight, molting, stress, broodiness, or age. Supplemental light and steady nutrition help maintain winter production.
How long do hens lay eggs?
Best production is in the first two years, then it gradually tapers. Many hens keep laying (fewer eggs) for years after.
How many hens do I need for a dozen eggs a week?
About 2–3 productive hens in season. Enter your flock and lay rate above for a weekly, monthly and yearly estimate.
What are the best egg-laying breeds?
Leghorns, ISA Browns, Rhode Island Reds, Australorps and Sex Links are all known for high, reliable production.
Do hens need a rooster to lay eggs?
No — hens lay eggs without a rooster. A rooster is only needed if you want fertilized eggs to hatch chicks.
When do hens start laying eggs?
Most pullets begin around 18–22 weeks of age, though it varies by breed and the time of year they mature.
