Polish crosses, 14 weeks, need help with gender

[ChickenGal14]

I have 3 polish crosses I hatched in July, I think the blue and the wild gold are Pullets (maybe..), but I’m unsure of this black/white.
thanks everyone

They all look like pullets!

They're so pretty!
I'm not good with Polish but that brown one looks like an EE with female coloring.

I'd guess all pullets but the hackle feathers do look pointy on the brown and black&white which would mean cockerels but I honestly can't tell if that's the shape or the lighting because they're so shiny.

All are pullets.
