i do it. my goats, rabbits and a few of my chickens share a pen and shelter. there have been some issues, from my reading in the past, with rabbits catching things from the chickens poo, but i haven't had any issues with that. i personally wouldn't house alot of chickens with them. but again it's a space issue. if you have a large area then i think it's fine or keep less chickens or less rabbits. i feel this is like anything else though, everyone is going to tell you bad stuff and good stuff and don't forget the really horrific stories too. so if this is something you want to do then do it. if you have problems adjust the environment until it works. i've never seen a rabbit eat feathers or chicken poo. everyone pretty much avoids each other till bedtime and then it's cuddle city. plus the rabbits come out to play most of the night and the chickens and goats sleep at night so everyone has plenty of room. i have gone out there during the day and seen a turkey sleeping between two rabbits. the chickens keep the bugs and flies down out there too so ya gotta like that. again if you want to do it, then read up on it, and do it. it's not hard to figure out if there are problems and then find a solution.
