I have a Red Sex Link roo in with my Dominique hens. I know that crossing two sex links will not produce sex link chicks, but what about a sex link crossed with a pure breed. The reason I ask is because the chicks that I've hatched out from my Doms which are about one week old are 50% all grey / blue and 50% grey/blue with a white spot on theirs head with some barring in the feathers. Are these considered sex linked chicks also?
