I am a new chicken mother hen. I have just discovered that one of my hens is actually a rooster. Apparently, the hatchery made a mistake, which I understand can happen. I have two Buff Orpingtons, one Black Australorps, and the rooster is an Aricauna/Americauna/Easter Egger. I am trying to decide whether or not to keep the rooster. I am raising the chickens for eggs and did not want a rooster for a couple of reasons (no eggs, crowing, etc.). I am wondering if my rooster would even be content in the chicken tractor. It is 4 ft. wide by 10 ft. long with a coop above the run. So far, everyone is getting along, but will the rooster eventually need more space? My chickens are 11 weeks old. Is there an ideal age to separate the rooster from the hens? Will there be trauma since they have been raised together? Thank you for any advice you can give me!
