My 2 girls turned out to be 2 boys, were fighting, had them neutered 5 wks ago. Reintroduced after 2 wks, fighting again (quite viscious) had to be seperated. Waited til now, reintroduced a couple of days ado. Spent about 30 mins fighting/playing - not nearly as viscious as before (or would have split them up), my partner said this was probably them just getting used to one another again and finding out who was boss. I've let them out together in garden twice since and seem to be pretty much stayin at opposite ends of garden, away from 1 another. Took them into house together tonight. 1 seems scared of other. Tried to keep away, kept running/moving away frm other 1. Seemed to me like other one jst wanted to play, but I wasnt sure, but then they came nose to nose, had a sniff, and the 1 who wasnt scared scraped the ground with his front paws and sprayed some urine backwards. Is this aggresive behaviour? At times the 1 who seemed scared thumped his back feet on the floor quite hard. Does any1 have any idea what all of this means? I am hoping to reintroduce them to share a hutch and run (they did when they were babies, they are brothers) and don't know if this is encouraging behaviour or the best route to take to encourage them to be friends again with an aim to living together? Any advice would be appreciated because I have never kept rabbits before, but I really love them and don't want to be upsetting them or to have to consider giving one away.
