Change the Chicken Coop to just a Coop.
Then make it so you can put rabbits in there, and make it so you can feed them with carrots only.
Then create male/female rabbits.
If they breed, the rabbits become "better quality" if you butcher them.
This could be useful for High Q Bunny Slippers, as well as Bunnies finally becoming something else then just food, but also pets and resources!
