What breed and sex are these? Pics included

Hi all

We have purchased some chicks today but I am unsure on what breed or sex these are. They have feathered feet but don't look like my other cochin chicks I have.

Chick 1

Chick 2

Chick 3

Chick 4

Do you know where they came from? Hatchery? Backyard? Farmyard?

The legs look pink--they could be Marans and Marans mixes. Perhaps an Olive Egger project?

Just a poultry auction so unsure
