what age for gender of australorps?

[TariOronar]

We recently got 8 Australorps. Ideally, we'd like them to be 7 pullets and a cockerel. But, since we got them unsexed, we really have no idea. But, itd be nice to know

Right now, they're just over a week, I know that that is too young to tell. They all just look kinda cute and fuzzy.

When would they be old enough to tell?
thanks!

I have australorps too...love them to bits!
I find by 5 weeks the little cockerels are starting to develop their combs and they have significant pink...not always 100% accurate at that age but usually can tell. If you post photos at around 5-6 weeks people on BYC are super helpful
The little pullet and cockerel below are at 5 weeks for an example....

I hope you enjoy your chickens....they are so much fun.
