What I understood from the OP is that she is trying to breed Silver Bielefelder, I did not see a picture of his Silver Bielefelder stock, just the gold Bielefelder she has(she mentions that she will be using the gold Bielefelder stock to produce more silver), when I asked what is the Silver line...
Due to the sex linked barring gene, the pattern will be different
More like the Silver Welbar(Autosexing Silver wellsummer)

So are you breeding an actual Silver Bielefelder rooster with the gold Bielefelder hens on the pics to produce more Silver Bielefelder stock? Or the Silver Barnevelder rooster over the Bielefelder hens?
