Not sure what breed?

[QueenieKay]

Hi there I am a fairly new chicken mum, with some 2 month old silkies and a few 1 month old chickens on undetermined breed.
I adopted these ladies from the local school, who watches them hatch for a project. They were not sure of the breed, but were apparently told by the person who supplied the eggs that they are not Isa Browns.
Any ideas?

They look like some sort of mixed breed to me.

They look like sex links but since the person donating the eggs said they are not ISA Browns then they are the offspring of sex links or some other male over ISA Brown hens. Which makes them barnyard mix. Sex links are hybrids to begin with.

The white bird with red shoulders is a cockerel.

I know one of them is a male wearing camo.

I think chicken in picture number one could be an Amberlink chicken.

they are a hybrid the Cinnimon queen/golden comet
one is a rooster and one is a hen
There parents are somewhere around these lines
Father - red - Most likely RIR
Mother - White - White rock or Rhode Island White
