I’m hatching chicks for a friend. They’re ‘supposed’ to be pure…

Just hatched these today for a friend. He was expecting pure Barred Rock, pure Rhode Island Red, and Americanas. I know Americanas are mixed anyways.

The yellow ones look like they have some brownish/red fluff although it’s not very visible in the pics.

Can any of you confirm the breeds of these chicks?
