My rooster will be 14 weeks on Monday. Could he already be trying to mount one of my pullets? They are not laying yet. The one he was after is red sex-link but she's only going to be 13 weeks on Monday? At first I thought they were chasing each other for a treat, but he was trying to grab her by the feathers at the base of her neck and there was no treat. He tried to corner her too. Can he even successfully mate her? Will he force her and injure her? He is not generally aggressive. I can't keep him, and I am keeping chickens for eggs, so if he is being mean, I won't pass him on, I will cull. No one wants a rooster who is already mean to hens at this age.
