I have an 8 month old barred rock rooster that is wonderful in every way except one - as soon as I let him and the girls out of the coop in the morning he is very er, forceful in his attentions. The poor hens can't even get to breakfast before he starts, and some of them seem to stay in the coop until he calms down. Is this normal? Is it because he is still fairly young? Something to be concerned about or not so much? He has 9 hens. He mates with them throughout the day, but never as aggressively as in the morning.
