I have a young drake and he has 4 young hens plus a grown hen in his little harem. He just became interested in mating the older hen in the last few days along with the oldest one of the "young group". My question is - Is it normal for him to groom all her feathers first as he sits on her? He will make them lay down and then walk around them "picking" or grooming at their feathers. If they try to get up he nips them on the head. Also one of the other hens will pick at them after he has done the deed. I never saw the older drake act like this so was just wondering.
