Yep, I have Orps and am completely useless at sexing them - have six week old chicks and can spend hours looking at them trying to work out which have the thicker legs or the more prominent combs. I think it changes every time I look at them. My current cockerel was an 18 week old hen, according to the 'experienced' breeder. Now you couldn't mistake him but he was at least 30 weeks before he started crowing.
