In this coop I'm trying out mixing rabbits with chickens. Basically what I have tried and with a degree of luck I say is a time sharing system. Both rabbits come out at night while chicks are roosting up above. In the morning rabbits go back inside the hutch and the chickens are free to run about.
Rabbits are messy, they don't use dropping boards, about the only thing I do not care for so far.
