Krystia, I'm in the same boat with my two boys. They had a 2x5 cage and multiples of everything, but still they couldn't be together without some fighting going on. After one lost a piece of his ear we said enough is enough and separated them. Now they both have 2x4 cages next to each other. I think this is the way to go. It would be more stressful for the pigs (and the humans!) if they were together and always were fighting and nipping. But more often than not when we walk into their room, they are laying side by side where the cages meet! They like to play by running and popcorning around their cages and meeting back at the divider. They will do this over and over for maybe 10 minutes, so you know they're having a blast. When it comes to floor time, we also do that separately. As much fun as you think they'd have together by how they act in their cages, as soon as that divider is gone and they can get to each other, it's all raised hackles, chattering teeth, and those yawns that say, "Look how much bigger my teeth are than yours!" So we just keep them separate, but within eyesight of each other. Also, their cages are one grid height off the ground so a lot of times when one is out, the other will lay down in his cage and watch. It's funny.

So anyway, my long boring story is just to say that separate cages can be the best option sometimes, and being separate might just be LESS stressful than being together. Hope that helps!

P.S. Like akstrohm says, keep trying to reintroduce them. We try every few weeks with ours hoping they will mature and settle the dominance issue. If they fight, keep them apart for now and try again in a few weeks. Good luck!
