More chicks - Barred chicks... this time! what are we?

[carousel]

Okay the background.
I ordered 3 Barred Hollands
I ordered 4 Rare Breed and 3 Heavy breeds.
I have accounted for 2 of the Rare breeds and 2 of the Heavys LOL
However I Have 8 Barred chicks!
I also however appear to be "short" 2 Australops <G>
Anyway,
what "I" can tell about these chicks
they all have straight combs, some have white chests some have gray chests. Some seem to have light spots some seem to have bands of white on their wings. They were all purchased as pullets.
Based on looking through Ideal's web page
the following chicks come barred and or cockoo and with straight combs.
Cockoo Marran, Barred Holland, Barred Plymoth Rock, and maybe a production black?
any thoughts???
they are 2.5 weeks old

Thanks for your help today on my chicks,
they moved to a bigger brooder today so I figured it was time to take some pictures!

They look like barred rocks to me... but that's only because that's a common type of chick and I've had those and not the others on the list.

look at the ear lobes barred holand will have white earlobes also cuckoo marans will have white legs compared to barred rocks yellow legs.

Nice chicks

GREAT suggestion,
at what point can I tell the color of their earlobes?
I think at this point, they seem to have yellow legs with some gray shading.
thank you!
