How it works

A good laying hen gives five or six eggs a week at her peak, fewer in her first molt, through winter, and as she ages. Plan for the low season, not the spring flush, and you will rarely run short. This planner works from typical breed averages and standard space guidelines.

Frequently asked questions

How many eggs does a chicken lay per week?

A productive laying breed averages 5 to 6 eggs a week in peak season. Heritage and dual-purpose breeds average 3 to 5, and most hens slow down in winter.

How much space do chickens need?

Plan for about 4 square feet per bird inside the coop and 10 square feet per bird in the run, plus 8 to 10 inches of roost per bird.

How many nest boxes do I need?

One nest box for every 4 to 5 hens is plenty; they like to share favorites.
