Rooster or not?

[Iceegg]

I'm new to this and this is my first batch of chickens and I was wondering if anyone thinks either of these chicks are roosters. I think maybe the rock but I not sure what to look for. The chickens are 9 weeks old if that helps any.

Both look like pullets to me.

They both do look like pullets, except one thing: Is the neck and head of your rock as light as it looks in the picture(much lighter than the body)? If so, I would think it might be a roo. It looks like there is a lot of difference in the darkness of its lower body and upper body. My suspected roo started to really start looking lighter colored at around that age.

Thanks for looking. I hope they are pullets and the light coloring is just due to the flash on the camera.

By nine weeks old it would be very clear if you had a little roo on your hands. They both look like pullets to me.
