Frequently asked questions
How many nesting boxes do I need for my chickens?
Use one nesting box for every 3 to 4 hens, with a minimum of one. Hens share boxes, so you rarely need one per bird.
What size should a nesting box be?
About 12 by 12 by 12 inches suits most standard breeds. Larger breeds like Orpingtons and Brahmas appreciate a bit more room.
Why do my hens all use the same box?
Hens prefer to lay where others have laid, so a few boxes always get more use. This is normal and not a sign you need more boxes.
