Some crosses using silver females and gold males produce offspring that can not easily be separated into groups of male chicks or female chicks. It is important that the breeder choose the correct breeds to use in making a red sex linked cross.
As a general rule, do not use autosomal barred birds ( Campine, Fayoumi, etc) or spangled birds ( Appenzeller, Hamburg, etc.) and laced Polish ( laced tail and single lacing). These birds carry the birchen allele which will not produce the down colors needed in a red sex linked cross.
The author carried out a red sex-linked cross between a silver Appenzeller Spitzhauben female and a Rhode Island Red male. The only way you could tell the difference between the male and female chicks was by a small amount of reddish or whitish color on the chin. On some chicks, you could not distinguish the difference between the gold and white on the chin. See Illustration 3 The back of the chick in illustration 3 is black; the black down is covering the reddish or white down making it impossible to determine the sex of the chick.
Not my quote this is from tadkersons sex link thread FYI
