parasitic white is Autossomal not sex linked .SO
if her son no name has no parasitic white ,than you can breed the white out by selecting the pure black progeny from Queen s and her son . each generation .
it is not a show .it is breeding as long as you balance the mating of your breeders in your pens , the fault will be bred out .for sure .
chooks man
I did check the cockerels yesterday. All of them have white under their hackles, even the ones with good copper.
