Estimated production
Estimate = laying hens × eggs per hen per week. Real output changes with age, breed, daylight, molt, nutrition, stress, and health.
About the egg production calculator
This calculator turns a flock count and a laying rate into eggs and dozens per day, week, month, and year, then shows how much is left to sell after household use and standing orders. It is built for anyone who sells eggs or plans to: farm stands, egg subscriptions, market vendors, and homesteaders deciding how many hens they really need.
How to estimate egg production
Count only hens that are currently laying, then use an observed weekly rate if you have one. The core formula is hens × eggs per hen per week. Dividing by 12 converts eggs to dozens; multiplying the weekly total by 52 estimates a year.
Use a conservative rate for sales commitments
Peak output is not the same as dependable output. Age, breed, shorter days, molt, nutrition, stress, and illness can all reduce laying. If you sell subscriptions or accept preorders, reserve household use and existing commitments before treating the remainder as sellable.
Worked example
Twelve hens averaging five eggs each per week produce about 60 eggs, or five dozen, weekly. After reserving two dozen, the planning surplus is three dozen per week.

Frequently asked questions
How many eggs does a hen lay per week?
A productive hen in her first laying year often lays four to six eggs a week, but the honest answer is whatever your flock has averaged recently. Breed, age, season, and management move the number a lot, which is why the calculator asks for your observed rate instead of assuming one.
Why does the monthly figure not equal weekly times four?
A month is 52 ÷ 12, or about 4.33 weeks. Using four weeks would understate a year by about a month of eggs, so the calculator uses the exact average.
Should I count pullets that have not started laying?
No. Count only birds currently laying. If you want to plan for pullets coming into lay, use the chicken laying age calculator to see when they will start, then add them to this estimate at that point.
How much of my production should I reserve?
Reserve household use, every standing order or subscription, and a small buffer for molt, heat, and short days. Whatever is left is the amount you can safely offer as new sales.
