I’ve been unsuccessfully trying to breed two of my rabbits for a while now. Both NZs, the doe almost a year old and has had at least three litters. Buck is not proven, and he is 6 mo old. It’s almost like he can’t figure out how to do it. He’ll go up to her, sniff her then sort of half mount before getting off of her, or he’ll just investigate her intently by puttin his nose and mouth all over her. The doe seems pretty receptive, shes crouching and sometimes circles the pen before crouching again. I can’t quite tell if she raises for him or not, but when I scratch her rump gently she rises up. Is there anything I can do to help him figure it out?
