Roos?

[Slgov13]

I bought them as premium sexed pullets from TSC but they're making me suspicious. They were labeled as Americana (so EE I assume). They are 6 to 7 weeks old. I am specifically asking about the mostly white one and the red and blue one. Little bitty spur? bumps on the back of the white ones legs, couldn't quite make out if the red one had any.
Thank you for the help!

Even hens have spurs. They just don't usually grow.

I would say pullets.

Red in the left is a cockerel. The other two are pullets.
