Difference between black aussie and black maran?

[goldielocks]

I know that the maran lays a darker brown egg but when i see the black aussies and black marans together i cant tell them apart. Did i get all black aussies?

A cuckoo Marans and a Australorp hen. Notice body differences. Carriage, feathering (besides color), legs and feet, top line and the tails.

 

[Harrietsmum]

Australorps will have slate gray legs.
