I've heard not to do this but do they have to be apart a certain distance so diseases can't transfer. I just got a bunny and wanted to put her outside but not sure what to do. My chickens are free range. Help? I've thought of a space I can block out for the rabbit with cage, the chickens wouldn't be able to get in but they will be around, would that work? I know of some that keep chickens and rabbits together, any ideas?
