I would say get a roo and hens of a breed known for good personality. We keep Buff Orpingtons, and the Roo, while wary and know to face off with the dogs if they get too playful, has never bothered the kids. Having a rooster with the hens has multiple benefits IMO, and worth trying to make it fit into the homestead. Some breeds are known to be aggressive and are great in the right situations. If you plan to keep them with young kids , I would look for young, non aggressive breeds that can grow up around the kids. Have the young ones feed them right from the start. Let the kids know if the roo does give chase not to back down. If it doesn't work cull the Rooster and introduce another if possible.
Good luck, there is nothing like seeing Steve, our rooster, call the girls over to a tasty treat he proudly found or have him eying the sky if a bluejay so much a chatters.
