I got my first chickens in Feb of this year. Our first 10 we bought from Atwoods. They were suppose to all be layers but when they were about 6 months old we found out 2 were Cornish Crosses. We culled one and realized they were to tough at this point to make it worth culling the other. Well a few months ago the rooster we got with them we culled because he was extremely mean. He would attack everyone and anyone. A friend of ours gave us a new rooster. He is sweet as can be to my girls. He treats them better then the other one. Well all expect one. He is mean as all get out to our last surviving Cornish Cross. Its not every day. But he has drawn blood spurring her. He chases her in to the coop and all around their run. I am really surprised that he hasn't caused her to have a heart attack. Is it because she isn't laying anymore? Or because she is such a big girl. Besides removing her is there anything else I can do to help this. She is healthy and I really don't want to cull her unless we have too.
