7 week old breed please

[Godscountryfarm]

They are from a local amish farm. We ordered many breeds and they were all given to us together without any Indication to what was which.
The breeds we ordered were…
ameraucana, black sex link, mystic maran, black copper maran , True Blue, olive egger, pearl star leghorn, light brahma, and golden laced wyandotte.

I have about six in that coloration. Please excuse the photo also as we have them all in the chicken Tractor ATM with the meat chicks while my husband works on their coop.
