I've recently been away for a month and I've just got my boys back. They've always gotten on so well, since I've got them back and whilst they've been away they've been really fighting, blood and everything. They have lots of room, run of the dinning room so there's definitely not a space issue. Do I leave them to it and hop ether settle back in or separate, I'm worried as one is limping and when they fight it's very vicious x I have two boy piggies brought up together since birth and now about I year old
