So here, I think, is a new one. I have both hens and rabbits free-ranging in my back yard. Tonight, when I went to collect my eggs from the chicken coop, I found one of my female rabbits sitting in the nesting box. I reached underneath her, and sure enough, she was sitting on 4 eggs, keeping them warm. It would be funny, but I'm pretty sure she's planning to have a litter of bunnies in the chickens' favorite nest box, which I don't think the chickens will be too happy about. Any suggestions?
