I know you don't have to have a rooster to have eggs, but if I'm not free-ranging my hens is there any ornitho-social-therapeutic reason to have one? Do they serve any other useful purpose? I only have 4 chickens and not a lot of space, and I really don't want a crowing bird. That, and I was attacked by a lot of roosters as a kid and frankly I don't like them that much. I have friends with oodles of chickens so if I ever want fertile eggs to hatch, I know where to get them. But I'm curious if there's a benefit for flock animals to having a male around. Any thoughts?
