Help me ID our chick breeds

[sksmass]

We got an assorted batch of chicks four weeks ago and most of them I can ID. But I am not 100% positive about these ones below and have been holding off naming them until I figure out what they are! Can any of you experts help me out by positively identifying the chicks in these pictures below (I've labeled the pics A through F)?

I'm new at this but fairly certain A is C and vice versa. Also I think the barred rock has the head spot. Everyone else looks right on.

I think I read somewhere that you can tell Dominiques and BR's apart by the comb.
Don't quote me, but I think Single comb=Barred Rock, and Pea comb (or Rose?)?=Dominique (sorry not sure about the Dom, but am fairly certain about the BR)
Also agree about A & C being reversed.
Awfully cute chicks!
