Eggs per week26.9
Eggs per year1400
Example
5 Leghorns in peak season lay about 1,400 eggs a year, roughly 27 eggs a week.
How we calculate it
Eggs per year = breed base rate Γ hens Γ season factor (winter Γ0.5). Per week = year Γ· 52; per day = year Γ· 365.
Based on:
- Productive layers average about 5 to 6 eggs per hen per week in peak season (Mississippi State Extension)
- Lay rate drops with short winter daylight, molt, and age (University of Minnesota Extension)
- Daylight length and light management drive laying rates (Penn State Extension)
Figures are typical guidelines for planning. Your birds, breed, climate, and feed will vary.
Frequently asked questions
How many eggs does a chicken lay per week?
A productive laying breed like a Leghorn or Rhode Island Red averages 5β6 eggs per week in peak season, dropping by roughly half in winter as daylight shortens.
Why did my hens stop laying?
The most common causes are shorter winter daylight, molting, age (laying declines after 2β3 years), stress, or not enough protein and calcium in the feed.
How many chickens do I need for a dozen eggs a week?
With a good laying breed averaging about 5 eggs per hen per week, 3 hens comfortably produce roughly a dozen eggs a week in peak season.
