In my somewhat limited experience with barred rocks (observing about 5 or 6) over the past few years I've noticed that they mostly seem to have an attitude, both towards other chickens and towards people. They're bigger than most of the others and they bully them. That said, our neighbors...
Greetings from College Station, Texas. Be sure to include Easter Eggers (Ameraucanas) on your list of desirable chickens. That is if you want good layers, and smart friendly chickens.
