I’ve had my rabbit Penny since Nov, and just today brought home my new bunny named Benjamin. I waited a while to put them together, everything was going good until he started to mount her. He was neutered 5 weeks ago (Penny has also been spayed), could this still be hormonal, or is this a dominance thing? Wondering if I need to wait longer for the male hormones to dissipate before trying another introduction? They seem to get along well sniffing and rubbing noses through the gate, which I think is a good sign?
