Can i bond 3 rabbits?

If all 3 are castrated is shouldn't matter if they are male or female, but its better to bond them while the hare is young, as this will make him or her naturally more submissive. Be sure to bond them in a mutual area, like a run or something. The only worry would be if the 2 bucks ganged up on the new hare. Be sure to have a spare cage or hutch handy in case any of them do fall out and can't be housed together. Like people, they won't automatically get on straight away, they need to get used to eachother and just hope they will get on after sometime interacting with one another. Hope this helps, and good luck with you animals!
