I think whenever I've kept two roosters in the same pen, one is dominant and the other submissive. Once when I got rid of an overly aggressive dominate rooster, his pen mate rooster "man'ed up" quickly. Prior to that I called him the cowardly rooster because he wouldn't even stay in line of sight of the other. I've heard of roosters sharing duty, but in my small confines that hasn't happened.Yes chickat I have two roosters, one is a wimp. The other is the one that attacked the goose.
