7.5 week old polish/creveocoeur sexes?

[and-roo]

These two are about 7.5 weeks old, I bought them straight run. Still not sure about their genders yet, could go either way. You can see their size in comparison to the wheaten maran pullet, they're both smaller than her, especially the SLP. I know it might still be too early but any guesses??

Their stance/posture screams rooster, but I can't be sure

They look female to me, but crested ones can be tricky sometimes. I'm not seeing any wattles popping yet, though theres a smidge of redness in the laced chick.
