I admit to knowing very little about how poultry genetics works and my understanding of sex linked birds is very vague. I have a chicken recently hatched out from two purebred bird. A speckled sussex rooster and either a white or buff orpington hen. The chick is primarily black with some white (looks pretty similar to a barred rock chick actually). What crosses allow you to determine the sex of the chick by color? Any chance with mine?
