Color and pattern male and female

Plumage: Primarily white feathers with fewer, preferably solid black feathers.

Down: Primarily white to sooty white fluff, with fewer less defined dull black fluff.

NOTE

Feather distribution should be predominantly white with black feathers. Black feathers should be evenly distributed throughout the entire body. This pattern should be clear and defined. An occasional black feather with white ticking or black feather with mottling may appear. The beard and muffs will often be completely white, which is acceptable due to the random distribution of single black feathers across the entire bird. Smokey colored feathers are to be discouraged but not a disqualification.

Serious faults

Any appearance of rust or straw in plumage. More than 50 % black feathers in the plumage.

Faults

The above serious faults occur to a lesser extent.
