I have 8 chickens that were suppose to be all hens. I have ended up with 7 hens and one Rooster. He is beautiful and I love the sounds he makes, however he has started to get aggressive only towards me. They are all 20 weeks old. I was wondering if it would get better as time goes on and he's not a teenager anymore, or will it get worse? I don't really want to get rid of him, but I don't like having to watch my back when I go in the run. Any help is appreciated.
