I need help sexing my chicks !

[Clucky Nan]

Hi I’m new here and this is my first posting so hopefully I’m doing it correctly!
I have a broody hen that has recently hatched some fertilized eggs that I put under her , they are now 10 weeks old and I’ve been trying to guess their genders since day one with no success.
If anyone could tell me what they think I would be extremely grateful there is 2 black , I light blue and a darker blue . I’ve attached a few photos of them all

I think the black ones are pullets and the blues are cockerels

Yes looks like both blues are cockerels and the blacks are pullets.
