Rhode Island Red Mixed Chicks - Hens or Roos?

[Km610]

I hatched 5 RIR mixed chicks. The person I got the eggs from has RIR hens, White Leghorn hens, Prairie Bluebell hens and mixed hens she has hatched. She has a RIR rooster so all the chicks are at least part RIR but some are likely mixed.

The chicks are about 8 weeks old and I am having a hard time telling if they are hens or roos. Someone please help.

The first two birds pictured and the bird in the foreground in the fifth picture are cockerels. Pictures 3 and 4 are pullets.

Seems pretty definite. I was hoping for at least 3 pullets. Oh well. Thanks everyone!
