marans or black sex link?

This chick is 7 weeks old. Is he/she a French Cooper Marans or a black sex link?

There’s another that looks similar behind her but has no white in the wings and has very pronounced tail feathers. I’m certain that’s a cockerel.

Both are cockerels.

White goes away at the Juvenal molt. The amount of red is a cockerel thing too
