Okay I started a new flock I got a couple Barred Rock and Rhode Island Reds mostly and I had one leftover Americana from my old flock the only one Barred Rock lived and he is a rooster and he picks on the one bird that doesn't match the rest the Americana I guess he hasn't looked in a mirror because he's a Barred Rock he's different to what do you think I can do to stop him from picking on her I throw food at him and he scatters but then goes right back to his behavior.?
