I wonder if anyone can give me some insight on my Pekin drake's behavior. He was hatched in April and grew up with a Buff female. In August I acquired 2 female Blue Swedish, and 1 Pekin female. In the beginning him and his little Buff friend ignored them. As they got older the babies would follow the two older ones about. Then they were all together. Probably the past 3 weeks he has been mating with all of them. I noticed he would have trouble mounting the female Pekin because she is bigger than he is. I noticed today he would chase her off from the rest of the group. Not letting her get water when they're all hanging about the water bowl. Chase her and poke her. In the coop tonight at bedtime he was chasing her away. They were all sleeping together in a corner, but tonight she is by herself in the far corner. What would cause him to be such a stinker all of a sudden?
