I'd love to let my bunny out in the run with the chicks once in a while but I asked on the rabbit website and they all said the chicks would hurt the bunny and they would give her salmonella. I know I've seen them living together in places before. I just wanted to hear the Chicken side of the story. They already know each other. The chicks get out to roam around the room while the bunny (Trilawnie) is out. She likes to wait until they are in a little circle and then run through them to make them scatter.
