I ordered 3 roosters from MacMurray when I got my group of 30 pullets in March. I have SEVEN roosters now (I'm assuming some mistaken sexing at the hatchery) and 35 pullets. They're all three months old now and I have TOO MANY roosters. What are the criteria you'd use (beyond looks) to evaluate which ones to keep? I ordered an Australorpe, a BO and a RIR. I have 2 BRs, 2 RIRs, a BO, an Australorpe and what appears to me to be a White Rock rooster. Some of them are starting to grab the hens by the back of the head so I want to clear them out before they get too aggressive. Thanks in advance!
