Are these hens what you guys in America call Black Stars? http://transcoop.com.au/wp-content/uploads/Bond_Black_Performance_Data.pdf
And are these RIRXAustralorps [I have no idea if the mum was an RIR or the dad was an RIR or the mum was the Australorp or the dad was the Australorp] also considered Black Stars? I a pretty sure they are 1st generation.

Black Stars/Black Sexlinks are a cross with a RIR rooster over a Barred Rock hen making sexlinked chicks, barred cockerels and black pullets with red leakage. If you got them from a hatchery, they are definitely black stars.

We got them from a local breeder. They are RIR X Australorp.

Oh. Not Black Star then. Black with gold leakage mixed birds.
