The best rooster that I have ever owned as far as running his flock, was a monster of a jersey giant. He was as calm as could be as long as he didnt think there was any danger. The kids could walk right up to him and pet him. But let any other animal enter the yard and see his rage! He never tried to attack a human, but he would "strut" and get between yo and the hens if you were getting them too excited.
