Any tried and true tips for sexing Olive Eggers?

[eanne06]

I've heard they're really tricky to sex. Mine are five weeks old and the waiting game is going to kill me! Their daddy is a Black Copper Maran and mama is an Ameraucana. My hunch is that A and D are roos, but I'm dying to be convinced otherwise. I got them from Mt. Healthy Hatchery, and they have a 90% guarantee, but I'm feeling suspicious. https://www.facebook.com/photo.php?...zyr53zZzKJrAGUoBSnJz0ZvykPKGlLBu6qWiDxI-f5Z3Y

A is the only definite cockerel I see but I'm using a tiny phone screen. I would keep my eye on D.

I'm afraid I do, too. Is there any specific to an Olive Egger that helps sex them? Have you had any surprises with cockerels turning out to be hens that looked like this?

There’s not really any tips because olive eggers aren’t a breed, they can be bred from any brown and blue layer which makes them a very diverse group. A definitely looks like a cockerel to me. The others look like pullets. It can be normal for the pullets of some breeds to get big combs early, but they shouldn’t be red like A.
