Frequently Asked Questions

For a dozen eggs per week, you need about 2-3 laying hens. A good rule of thumb is 2-3 hens per person in your household for regular egg supply.

Top layers include Leghorns (280-320 eggs/year), Rhode Island Reds (250-300 eggs/year), Australorps (250-300 eggs/year), and Plymouth Rocks (200-250 eggs/year).

Plan for 2-3 sq ft per hen inside the coop and 8-10 sq ft per hen in an outdoor run. Bantam breeds need slightly less space.

No. Hens need 12-14 hours of daylight to lay consistently. In winter, you can use artificial lighting to maintain production, but many keepers allow a winter rest period.
