I have a young rooster, only a month old, who keeps attacking my other chicks. I have 3 roosters, maybe 2. But the oldest rooster is calm and does just fine with the others. But I have one that will just fly at my pullet and peck her. I saw him do it 3 times in less than 10 minutes. Should I get rid of him? He makes a lot of noise when hes separated from the rest of the chicks, but I don't want an aggressive chick. I'm not sure what to do
