Maran cockerels or pullets?

[Lvbowen]

I got three straight run marans, 2 blue and 1 black. I was hoping for pullets but I'm starting to think they are cockerels. Especially the black one. I'll attach two pictures of each and I'll appreciate any help I can get!

No one's screaming cockerel but it's early to be sure. About 5-6 weeks is usually good to tell Marans males.
