Ralph, I am also interested in producing sex-links. I keep snakes so the males will still serve a purpose as snake food, and I would then only have to raise the females. Win-win since snakes have to eat too, and it saves me money on buying snake food, if I can produce my own.
With that in mind, I've done a little research and found the following thread to be very helpful:
https://www.backyardchickens.com/t/261208/sex-linked-information
Some of the paragraphs that were more pertinent to me:
Quote: (The first rule was a very long paragraph that basically said sex-links don't breed true - something of which I was already aware.)
Quote: This is what Danz was referring to about the white rocks needing to be silver based.
Anyway, I won't quote too much since the link is there so you can read on as much as interests you. My main cock bird is a New Hampshire so I am halfway there. My other cock bird will be a Barred Rock (when he grows up - he is currently only a few weeks old) and from him I may be able to produce black sex-links as well.
