Mille fleurs d'Uccle; 4 ½ weeks old, pullet?

[Ganesh-Saahd]

Hello hello!
I have 6 baby Uccle, 2 different age.
Among my youngers, there's one that I cannot decide if it's a boy or a girl.

What do you guys think?
Her/His brother is very obviously a brother

Edit: I added 2 last picture: the porcelain one is the brother. The other Mille-fleurs is a pullet

Still early but I think pullet at this point.
