Sexing d'uccles and wyandottes

[Thelocalladies]

Hi there! Just wondering if I could get some advice on these 4 week olds (young, I know). With my eggers and orps I remember being able to see some differences in the combs and legs... but these guys I just really cant tell. Any advice?

Note: I'm aware one of the wyandottes has a single comb and is considered incorrect

Nothing is screaming cockerel on any of them at this point.
All are looking like pullets for now…
Update in 2 weeks with more photos.
