Baby Chick Gender

[Jacobt]

My 3 week old Black Autralorp and Blue laced red wyandotte. Do you guys know their gender? I think the autralorp is a hen, but I'm worried the wyandotte is a roo. Its legs and basically everything is just all around larger.

The Australorp is a hen, and the Wyandotte I think roo

From what I've seen with my chicks, the cockerels tails grow a lot slower than the pullets. So based on that, the Wyandotte is most likely a cockerel. But I'm no expert.
