I have 2 rabbits both of wich are housed with my chickens. I have two runs connected, but separated. One is the chicken run and coop and the other is the rabbit run and hutch. The rabbits have dug under their run into the chicken coop, so they can go back and forth, but the chickens cannot. Everyone gets along just fine. They don't really seem to be bothered or even notice eachother. I have noticed the rabbits prefer spending the days in the chicken run and the nights in their hutch in their own run.
