I have a flock of pullets with one rooster, they are 4 months old yesterday. The rooster started crowing about 3 weeks ago and use to crow alot through out the day. But I have noticed that when he crows now one particular hen will attack him... Pecking and flapping her wings at him. Then she goes off on her merry way until he crows again, then she runs up and starts hen pecking him... I have never seen this before or heard of such a thing, anyone else seen this behavior? He has gotten so he hardly crows except at night and early morning...
