I agree with Sue25. I have my bantams in with 'biggers' as I call them, Welsummer and Buff O hens. No problem. The Wellys are a little 'pecking order' obsessed but all in all they get along very well. In fact, the Welsummer hens beat up the OEGB/BBR cockerels that I have regularly. Not too easy on the OEGB cockerel's egos but funny as all get out to watch.
