Kaczka pattern

Pręgowany puch

Down pattern of the young of wild-colored poultry: dark brown to black stripes running down the crown and back between lighter buff or yellow stripes, often with a dark line through the eye, on a pale underside: the 'chipmunk' chick of partridge and black-breasted red breeds, the Mallard and Rouen duckling. Lost when the first feathers come.

No Kaczka breed lists Pręgowany puch yet. No club standard describes it.
