Pullets or cockerels

[Cinnamon11]

I have recently added 3 chicks to my flock and they are now 3 weeks old. They are supposed to be sexed females but I am wondering if any are cockerels? The breeds should be a white leghorn, cuckoo marun, and a surprise but I think she is a blue cocin. Is this right?

Yes, the last one does look like a blue cochin. For gender, you have to wait until they are 6-8 weeks old. It's too early to tell at this point.
