Is my 7 wk Australorp a roo?

[Obleo]

I am very confident in saying that the two Australorp’s you show in the pictures if them at 10 weeks are both pullets.
By looking at the pictures, nothing about either of them looks like a roo, unless you have an extremely slow maturing roo, which I doubt.
At 10 weeks an Australorp roo is obvious, red wattles and comb, tail feathers are developing, diameter of their legs are much larger, noticeably larger than a pallet of same age, etc, etc.

What would you say these are?
