This is not my theory at all. I read this, probably on this website. I have had 2 and 3 roosters at a time, and they have managed to live together - not harmoniously, but without constant battles, once they learned their places! The GCM roosters were the most cooperative and congenial that I have kept.I would be interested to know if you are correct with your 3 roosters, but not 2 theory. I have 3 cockerels right now. They all get along just fine, but I know they have not matured. I have 11 chickens in all. Seems like everyday a hen turns into a rooster!! I'm going to have to rehome a few guys here soon.
