So far I have 24 birds, but I am giving away a couple hens and I have lots of roosters, so I am not sure about them? So far they have been so sweet and tame, I have 6 bantam roosters (very loud and early crowers) and 3 blue-laced wyandotte roosters that are becoming quite handsome. If they start to be aggressive they will have to go, but I love them!
