One of a kind since 1929

Buck and Daisy Rabbitry offers the Black and the Blue varieties.

From wikipedia:

Weighing 9–12 pounds, three color varieties are available in this breed: black, blue, and chocolate (A Minnesota breeder is currently working on the chocolate, but they are very rare), black being the only one recognized by the ARBA's Standard of Perfection.(As of summer 2008 the Blue variety can be shown. It is in development.) The Silver Fox's fur is coarser than the fur of other rabbits, one and half to two inches long, and when stroked from tail to head, the fur stands up. This is referred to as "no flyback" fur. The guard hairs are white. This combined with the length and coarseness of the fur resembles the fur of the Arctic Silver Fox for which the Silver Fox rabbit is named. The Silver Fox Rabbit is listed as "Critical" by the American Livestock Breeds Conservancy, meaning there are fewer than 200 annual registrations in the United States and estimated global population less than 2,000. The silver fox is a commercial breed. They are born without the silvering (solid color)and their coloring silvers out later as they mature.
