What breed are these 10 week old pullets?

[pinknblackchaos]

I just re-homed a rooster to some beginner chicken owners who had some pullets of a similar age. They didn't know their breeds to well and told me they had 2 isa brown's and 2 barred rocks. They sent me a picture of my welsummer roo with his new ladies and i am not sure they are what they think they are. I have had barred rocks and they were barred already and these are full black and the "isa browns" are cream colored. Please help me identify these pullets for them.

Black sex links and white rocks are my guess. Bsls and barrred rocks are identical at birth

If they're solid black they may be Australorps. The white ones look like White Rocks, but I can't tell if they're solid white. They could be Amber Links, mine didn't actually look like it until 12-13 weeks.

The whites look like white Plymouth rocks and the black ones are Australorps

Australorps and White Rocks most likely. Need better pictures to confirm.
