My son and daughter were given a 6 month old doe rabbit. Daughter named her Bella. DH hates caged animals (won't even go to a zoo because of this). So he has let her run free in the chicken yard. The yard is completely fenced/dug in to ground to prevent predators. The yard is 20x80 rectangle. Bella loves it and she doesn't bother the chickens and they don't bother her. She runs back to her cage to eat/drink which is on the ground and always open for her. The chickens never go in there but will stick their heads through the cage to get a few grapes I give to Bella, so I have to wait to give her treats til night when the chicks go to roost inside their coop. Is there any reason Bella should not be allowed to run free with them? Are there any diseases they could pass to each other? There are no other plans to increase the bunny population so she would be the only one in there. Anyone have any ideas???
