*Please do not choose a feather sample for Silkies who do not yet have real feathers. This does not work with chick down. Please use blood spots on a plain piece of white paper or an index card for birds that are not old enough to have real feathers yet.
About Dun
Dun is a mutation of the PMEL17 gene that dilutes black into a warm chocolate-gray. Two copies dilute further than one, so the same pairing can produce birds that look quite different from each other.
Dun is regularly mistaken for the chocolate gene. Chocolate is sex-linked and sits on a different gene entirely, so the two follow completely different inheritance patterns. If you are trying to work out which one is in your line, this test answers the Dun half of that question.
Dominant White and Smoky are separate mutations of the same gene and are sold as their own tests.
