I have 22 in 4x8. Automatic door with photo sensor. They come out first thing and do not return until night. I started with 3 nesting boxes. Added 3 more they still only lay in 3. Chickens will do what they want and as long as you turn that space into roosting for nights you are good. My chickens were out all winter even down in the -25 degree temps we had. They are hardy animals and we do not give them enough credit for being able to care for themselves. Mine free range on 5 acres during day. Currently have 5 buff Orpington. 1 Silkie roo, 3 Wyandot, 3 barred rock, 4 RIR, 4 Delaware , 2 light Brahma. I have 3 roosts running 8 ft and 4 roosts running 4 ft. Staggered all above 4 ft with mini roosts to jump up to top. Good luck!
