Hello! I just bought a new rooster for my flock last night. He is a cochin... less than a year old. I have them in the chicken run in a separate Coop away from the girls during his quarantine/introduction period. He was making some clucking noises when I brought him home, but I have yet to hear him crow. is it normal for a rooster to not Crow for a while in a new flock? He's our only rooster and I have 5 hens.
