I have 18 hens and HAD 1 rooster. He became very aggressive towards me and literally tore up my hens. It will be a while before they re grow their feathers. I had to cull him this past weekend after he went for my face. He was a huge NJG. The whole atmosphere in the flock is so much more peaceful but is it ok for them to not have a "leader" for a little while? I will be hatching new chicks from eggs I got on BST in a couple weeks, no doubt there will be roos in there.
