Black Australorp chick comparison?

[Lochness Monsta]

Let me start by saying I know it’s early! But I’m wondering what everyone thinks about my 2 australorps. Same hatch date — both just over 2 weeks — but one is much larger. Anyone think she’s gonna be a roo? Not the best pic I know. Also included their legs for comparison.

TOO young. A guess right now would be just that, a blind shot.

Obviously too young, but I'll take a guess and say 2 pullets.

It can't be said to be definite, but my Blue Australorp boys had significant comb development by 3 weeks:

Its a bit young, but I'd say roo because of those thick legs. My Australorp rooster had legs like that at three weeks old.

I know it’s too early, just having fun and speculating

Thanks for the guesses!
