I heard from one of my earlier posts if you put a lot of males(rats) together they will fight IDK if this is true but if it is then that wouldnt be such a good idea
You can keep multiple males together, but I'd only recommend doing it if you're raising males together from the time they're weaned. You don't want to take a bunch of big breeder males & throw them in together after they've been in with females - you'll have some serious fighting going on if you do.
