White rock often carry dominant white and sex linked barring; these two genes can not be found in black sex linked cross. You would have to do a test cross to determine if the white rock male carries the two genes.
Cross the male with a black bird (any breed). If white chicks or barred chicks are in the offspring do not use him. I would hatch at least 10 birds.
