I have inherited an Angora bunny and would like for him to have access to the outdoors. Would it be safe for him to play in the chicken run with the hens in it as well? Or can you free range bunnies too? He has his own "room " in the chicken coop, 4"x 4" space. Owning rabbits is very new to me, I've only owned cats, dogs, rats, and chickens since June of this year. Any advise or help would be greatly appreciated.
