Pullets or cockerels?

[Chickie friend]

We bought three chicks on July 25. They are 5 weeks old and I was wondering if someone could tell what their gender is. We bought them as pullets but we aren't so sure about the buff orpington. . . . The first one is a cuckoo Maran then a barred rock then a buff orpington.

They're still a little young, but I'll say pullets for now.
