Great post, I've not been able to find alot of information on this elsewhere in the past. We had two male rabbits, at first they got on really well, but once the smaller one had got to about a year old he'd had enough. We came down one morning to a bloody scene where they'd been fighting all night. We had to then keep them totally seperated, which was just a bit sad to see as the eldest one still really loved his little brother!
