Silkies appear in two distinct varieties: bearded and non-bearded. Bearded Silkies have an extra muff of feathers under the beak area that covers the earlobes. They also are separated according to color. Colors of Silkie recognized for competitive showing include black, blue, buff, grey, partridge, and white. Alternative hues, such as cuckoo, lavender, red, and splash also exist. The standards of perfection call for all Silkies to have a small walnut-shaped comb, dark wattles, and turquoise-blue earlobes. In addition to these defining characteristics, Silkies have five toes on each foot. Other breeds which exhibit this rare trait include the Dorking, Faverolles, and Sultan.
