Some breeds will have a higher % of human aggressive cocks, but still, it can be an individual's little brain that makes the difference. Salmon Favorelles, Cochins, and Brahmas tend to be pleasant, while production reds, EEs, and New Hamps tend to be tough. I've had nice Australorps, Chanteclers, Ameraucanas, Speckled Sussex, and Jersey Giants. Also individuals that were jerks, and tasted great! I like to raise my own rather than getting an adult, so I watch them grow and make my picks gradually. Any human aggressive cockrel gets culled! Some cocks will become difficult the following spring, and they leave too. Mary
