The roo is the Australorp. So hypothetically, if it is sexlinked and the roo is solid black, these would both be male? Assuming that the hen is a Delaware.The Columbian pattern of the Delaware is dominant, with one, or two copies, but has stronger effect with 2 copies. But it also depends on the genes of the other bird(s) in the mix.
Australorps are Extended Black which is also a dominant gene. Extended Black is dominant over Columbian, & many other genes.
So, Australorp Hen X Delaware Roo = 100% Barred, Black offspring.
They plus any other breed will produce 50%(Maybe. I'm bad at percentages), Barred Offspring.
Sex links if a solid Male breeds with a Barred hen though.
The chicks may resemble a Barred rock in coloration.
