Blue Australorp x Blue Star = barred chick?

[imacowgirl2]

Blue Stars from Ideal are a cross between a Blue Andalusian and a barred rock, according to their website:

If a Blue Star hen was bred to a Blue Australorp rooster, could that pairing produce a cockerel that is colored like a barred rock?

No

The barring gene makes white lines across the feathers, and also makes a white dot on the head of the chick. The barring gene is on the Z sex chromosome, so careful choice of parents lets people produce sexlink chicks (where one gender has barring and the other does not, so they can be sorted by their appearance from the time they hatch.)

For that cross, they use a Barred Rock hen, and a Blue Andalusian rooster.
The male chicks have barring (indicated by the "white dot on the head" in the description) and the female chicks do not.

If you cross a Blue Star hen (no barring) with a Blue Australorp rooster (no barring), you get chicks with no barring. They might be black, blue, or splash, but they will not have barring.

If a Blue Star hen was bred to a Blue Australorp rooster, could that pairing produce a cockerel that is colored like a barred rock?

If you have a cockerel colored like a barred rock, he must have at least one parent with barring.
