Maran chicks. What kind? And hen or roo?

[Chicklady720]

So I bought these as marans. She said one of them was blue. Is the other a wheaten maran?
And do we think hens or Roos? They are about 4 weeks old.

I see one cockerel one pullet so far. They are quite young though, so wait a while for the one in the last photo
