I have 3 barred rock rooster about 10 weeks . Right now I have them with my hens and those little bugger pick on my hens. Sometimes I take a chair and sit with them they will jump on the chair and act like they want to be petted or pick up and when you do they bite and if I ignore them they will jump on the back of the chair and bite my ear. They are going because I can't keep roosters. My neighbor has some also and I ask how she like them she said the same thing they are ninnies
