Gender on this 6wk old mixed breed

[Ebz5003]

I have a 6 week old chick that I hatched from my Egyptian Fayoumis hen and Biff Brahma rooster. I am not sure about the gender. It was hard to get pictures as the bird is flighty, like his mother, but I posted a few. It has barring on lower body ( wings, tail, etc).

Can you tell me how you know it is a pullet?

Her comb and wattles are very small. Males would be getting bigger and redder combs at this age.

Ah, okay. Makes sense.
