Fun! Assorted brown egg layers. Help me learn who?

[MIChickandGuinea]

I have a shipment of brown egg layers from Hoover’s and I am having fun trying to puzzle out who is who. I have taken pics sort of by chick color... to narrow the field for sleuthing a little. Here are the basically black chicks. The one on the left looks more black/yellow/white, the one on the right looks more black/grey/white. Possibilities from their listed brown egg layer breeds are:
Black sex link, barred rock, Dominique, Asian black, black jersey giant. I don’t see yellow on any of their black chicks in the brown layer reference photos. Left chick maybe looks like black Marans to me?? And the right one ...???

They appear to be Barred Rocks (if single-combed...Dominiques sport rose). Chicks of black coloration don't have head spots. Just gorgeous!

agree with @Alexandra33 on the barred rocks or dominiques... depending on comb. Marans all have white legs, and these guys look like they're yellow.
