Australorp chick or something else?

Hello, this is Pepper, I'd love to know what breed she is, she's 3 weeks old, I got her from a feed store which does not list any breeds, just that they're sexed pullet chicks.

She looks very Australorp like (they lose the white by about 10 weeks), but I noticed her comb is almost slate-like. I'm wondering if she's a mix.

Australorp is my guess.
