Feathered feet, anyone know what breed? 11 weeks old

[Chold05]

Hi everyone!
11 weeks ago we got our first chickens!
2 cinnamon queens, 2 ISA browns, and 2 “Sapphire Olive eggers” according to the sign from the place we got them.

However, I can’t find any photos of sapphire olive eggers with feathered feet. any ideas what our girls might be mixed with?

Almost looks like a French cuckoo maran... don't know much about that specific breed, but that's what came to mind. Could be a cuckoo or barred cochin as well.
Whatever it is, definitely not a sapphire olive egger.

A Barred Cochin? "Interesting"
