Hi, I don't know everything about chickens and bunnies. I have had my hens for over a year and my bunnies only a few months. I have a coop for the chickens on one side of a large treedfenced chicken yard and a large rabbit hutch (2 feet off the ground) in the middle of the yard. In the morning I let them all out and in the evening I put them all up in their respective locked sleeping cages. They seem to get along fine. Every now and then a hen will give one of the bunnies a peck, nothing hard and not often and less and less as time goes on. Right now everyone is very healthy. The bunnies are very hard to catch at night so every now and then I leave them in their hutch during the day. They haven't tried to dig out yet. They seem happy with the situation and I love to watch the bunnies stretch, hop, zig zag, flip, run and play. I haven't noticed the bunnies eating the chicken food. I don't use medicated chicken feed, but the bunnies have plenty of bunny food and hay which they prefer. Also, they can jump into their hutch during the day if they want to and sometimes they do.
