This is my Orpington hen. She lays 4 to 5 eggs a week. So just because an Orpington has a big comb and wattle doesn't mean its a roo. I have seen so many people talking about killing young birds that look like hens because, they think they are roos. Anyway take a look at my hens pics if she didn't lay eggs I would think by comb and wattle she is a boy. You really can't tell with Orpingtons unless they start rooing or laying eggs.
