Are they for sure pullets?

I have four chicks, RIR, Barred Rock, Gold Star, and EE. I'm pretty sure they are all pullets, but I'm new at this and would love some verification! I couldn't get the EE to look at the camera, she's shy. They are about six weeks old. Thanks for any input!

They look like pullets!

Thanks! I feel like they are, but don't want to be wrong. We can't have roos, and we are already so attached to these!

I know how you feel!
