Two of my pigs started fighting today. They are Mellow, male, 1 1/2 years old and his baby boy Baby Bandit, almost five months old. I'm assuming they're fighting because Baby Bandit is reaching puberty. They haven't hurt each other, but it scares me (they also make a huge mess running around). What should I do? Will they stop fighting once one of them has established dominance? They've always got along real well and I know they like each other (they hate being seperated even for a moment), so I would rather not put them in seperate cages. Advice?
