Black Langshan x ? hybrid or Black Marans? 8 weeks old Roo or pullet?

[zantroo]

I bought 5 Black Marans pullets from Estes, but I forgot (dummy me!!!!) to look at their legs before I put them under the hens to mother to ensure they all actually had feathering. Now I can't tell the Marans from the other 7 black chicks that are Black Langshan-fathered hybrids with BA or Langshan moms. There are a few that don't have single combs so I'm sure they are some of my hybrids.

Chick #1

Chick #2

Chick #3

Chick #3 again different angle male or female as well

Chicks #4 & 5

Chick #6

Chick #7

The Marans are all black in the face while the BA cross has red wattles and combs
