I bought two Buff Orpingtons from Agway. After viewing other posts I'm wondering if the gold one is a roo. Anybody care to give an opinion? The gold one is about four weeks old and the I'm guessing by the late feathering that the white one is three weeks. I'll try and show the comb and waddles in the pictures. Maybe it's just too early to tell but Agway is willing to exchange the bird if it's a roo and I don't want to wait too long. Thanks.
