Sex and breed of chicks?

[Joshy1718]

I have these three chicks. Can you help tell the sex and the breed? I’m pretty sure the brown one is a partridge Cochin, but not sure of the other two? Thanks!

Waaaaay too young to tell gender.
They all look to be Cochins, not sure on colors.

It’s too early to tell what sex, and I’d like to tell you the breed but I don’t know any breeds except for brahmas that have feathered feet, and those don’t look like brahmas
