For black sexlinks, it's not the color of the rooster that is important. He just can't be solid white, that would hide the evidence of barring, or barred/cuckoo, since he would pass that to both his male and female chicks. It's the hen that is the important part of the equation. A barred/cuckoo hen can only pass that barring to her male chicks.
Sexlinks are mixed breeds, and therefore, can not be considered 'heritage', regardless of the parent breeds' lineage. The term 'heritage' generally refers to the stock being bred to the breed standard. Since there is no breed standard for sexlinks, due to their being a crossbreed, they can't be heritage. It doesn't really matter if the parents are hatchery sourced or heritage stock. The color genetics for the sexlinking are still the same.
