The Biro and the Golddust are Biewers of alternate coloring as compared to the original Biewer which has black marking. We are breeding Biro to Biro to maintain the brown markings. The Golddust that we have now are just the luck of the draw. One of our males carries that particular gene and our standard Biewer had 4 normal Biewers and 2 Golddust. We may eventually breed Golddust to Golddust to keep their unique coloring. But as of this time we do not have a non related breeding pair to work with. I do know that some Biewer breeders now have some Golddust in their breeding program and are reproducing Golddust to Golddust puppies. |
