Gender of chicks?

[Cheepins]

gender of these chicks? One is golden laced Wyandot others are amber links, They are 10 weeks almost 11 weeks old, bought from tractor supply, told they were female. They all have small nubs on their legs I’m wondering if they are roo’s? Fingers crossed!

I would say that the two brown on the right in picture #4 are cockerels.

Can some tell me if this Wyandote chick is a pullet or a cockerel?
