The original colours are black, white, buff, blue and splash. Although there are many additional varieties recognised throughout the world, only the original colours are recognised by the "American Standard", the Buff being the most common colour. In the beginning of the twentieth century, Herman Kuhn of Germany developed a Bantam variety. The Bantam retains the appearance of the full-size bird, but in a smaller size. There is a large variety of colours in the Bantam version, including black, blue laced, white, buff, red, buff black laced, barred, buff Columbian, and birchen. The Bantam retains the friendly personality of the Standard breed, and seldom or never flies.
