I've got 3 roos and 31 hens. There is definitely a dominant rooster - my bantam cochin - who runs the other two around (a standard polish and a silkie). But they don't fight, and since they free range they don't have to be anywhere near each other. The only time I see a squabble is at bedtime when they're going to roost. The bantam won't let other two into the coop until he's chosen his place to sleep.
In the past, I had two brother roos who had grown up together. I got them as adults. They did fine until spring, when one day they just started fighting and fought all day. But a day or two later, all was good and peaceful again. Occasionally, once every few months maybe, they would fight but not usually.
