Sorry, this only works for black (why they are called black sexlinks). There are other types of sex linked genes, but I doubt you could find the right genetics in silkies to make any other sexlinks. If you cross white to cuckoo, you will likely not see any white without extra crosses to get it back. Whie in silkies is recessive white and it covers everything, including black and barring, so it is possible for a white silkie to produce barred chicks if crossed to a black bird, if it is hiding the barring gene.
