how old are they?
I have lots of hobs that I use, some live together and get on fine, others have to be split in the summer as they fight, but come winter, all get housed together, if you want to keep them together as a team, get them castrated, that will sort it, I have four hobletts (no bollocks) great workers for summer time when intact males just want to fight or mate,
the albino is two years old and the polecat is one year old.
