2 month old mutts - roos or pullets?

[gogetter]

I have a several chicks I'd like help sexing. The first two are welsummer mixed with a red and white unknown origin roo. The third one is from my black star covered by the same unknown origin rooster. They are 2 months old. Their behavior makes me think roos, but their combs are all pretty small and pale. Any help is appreciated! Pictures of a brother who has already crowed, and the unknown origin daddy of all of them are at the end.
Chick#1 "dotty"

Chick#2 "ginger"

Chick#3 "bronco"

This is their brother who started crowing at 7 weeks:

This is dad:

I don't think you have to worry, all three birds look to be Pullets.

Enjoy!

They all look like pullets to me, too (except for the obvious crowing cockerel).
