OK, my Buff Orpingtons are 18 weeks old now. None are laying. I am positive 3 are roosters (which we plan to eat), 4 are hens for sure, and the other 3, well, I'm not so sure. I have 3 that are similar to this, large red combs and waddles, but tail feathers just kind of lay flat over its rear. This one looks like a rooster to me, poofing tail feathers. Then this one in the middle of the frame, looks like an obvious hen with her pointy tail feathers, and lighter smaller comb.
