Purchased a mix of 15 “pullets” last August. They were sexed with a magnet on a string and we’ve already brought one rooster back, have at least 3 more with obvious tail plumes who are facing off and I’m wondering about these 2. The big one I saw grabbing a couple hen’s necks and I think trying to mount, but others in my co-op think it’s just a big mean hen. Could really use some help!! Sorry not sure the breeds.
