Geez really?? I'm new to chickens these ones are my first, but I'd have never guessed that that is what he was doing. The girls do not seem happy about it AT ALL.
I have a 3 and a half month old Buff Orpington rooster, he is very sweet to me, he eats out of my hand and will sit in my lap for hours if I let him, he even follows me around the yard. But recently i have noticed him getting aggressive with my hens. He bits them! He bits the back of their necks...
