Silkie chickens - hen or too?

[SOdwizzle]

I have 4 Silkie chickens I’m looking for opinions on gender.

All are 13 weeks old.

White (Flash)
Black (Peppermint)
Brindle? I don’t know what it’s considered (Freckles)
Tiny Mohawk (Smokey). So Smokey was scalped as a chick and as a result has very patch bald spots on her head. So I can’t really use her head feathers as an indicator.

Any guesses?

In my opinion, those are pullets. The "brindle" one looks like a partridge Silkie.
