Some people apparently have roosters with hens that get along peacefully. I wish that had been the case for us, but while our roosters were fine together when they were young, that stopped as they matured. We had to form two separate groups so that the roosters could not fight each other. Be prepared, when roosters fight, it can get very bloody. One of ours even almost blinded the other in one eye (but still neither one became submissive). I hope that yours stay friendly with each other, but brace yourself and decide what you will do, because it could go either way. And when they need separating, they need it immediately.
