Light Brahma Cockerel or Pullet? 5-6 weeks

[K_mc2818]

I have a Brahma that is 5-6 weeks old. It follows around a little cross-beak chick I have that is the same age, almost like it’s “mothering” it. Any thoughts on the gender?

Definitive Pullet. Not much black in wings and tail feathers. Head also pullet.
