I've experienced the same thing myself. It may be temperature dependent. I love seeing babies with their mothers, but I don't hatch my own chicks for that very reason. I'll admit that I've been spoiled by the modern broiler industry and by comparison, roosters that aren't broilers aren't worth eating. Even large breeds are more bone than meat and IMHO aren't worth raising. Roosters are beautiful and if I accidentally get one in an order of "pullet" chicks, I will usually keep him because he is nice to have around. But if you have more than one, they begin fighting as they get older if hens are around. Again in my opinion, if you want a sustainable meat bird, ducks are the way to go. You get a much better meat to bone ratio and in hatching my own ducklings, I seem to get close to a 50/50 duck to drake ratio. As for chicks, I prefer to get pullet chicks whenever I want to start a new flock.
