My one rooster and 5 hens are 15 wks old and live together in a large coop and attached pen. My rooster gets up first and the first hen to exit into the pen gets picked on by him. Now all the hens seem to stay on the roost for a good long time in the morning!!!No on seems to want to deal with "boss" in the morning because he bullys them by chasing and grabbing at their feathers. Is this normal? Any suggestions to make a better morning for my little hens? He jumps down and exits when I open the door to the coop. At that time I put food in the pen and one scoop inside the coop. The girls keep sitting. He doesn't appear hungry just nasty in the A.M. Thank you for any input.
