Hi, we used to have 4 male piggies, they were in 2 pairs with one dominate over the other, recently both the submissive ones died and I've tried to introduce the 2 Alpha males to each other. We gave them both a bath and we washed out their homes, and bowls and igloos. We have a big run, (6ft by 3ft) and they're housed in there now. At first they seemed fine but then they've started to square up to each other, teeth chattering and one chasing the other. I hate to see them fight but I'm after some advice on what I should do. At times they seem fine as in they know the other one is there but they don't play or cuddle up with their old buddys. I'd hate to seperate them as I think they'd rather be together with their own kind.
