DNA Testing – Mottling Gene

Price range: $18.00 through $1,600.00

Mottling Gene (Mo) PCR Test

Determine if your birds carry the Mottling gene that creates beautiful speckled patterns!

The Mottling gene (Mo) in chickens is responsible for creating attractive white spots on feathers, giving birds a speckled, mottled, or pied appearance. This simple PCR test detects whether your bird carries zero, one, or two copies of the mottling gene—providing valuable information for breeding decisions.

Test results:

  • No Mottling gene (wild-type) → solid plumage

  • One copy of Mottling (carrier) → partial mottling or hidden in certain breeds

  • Two copies of Mottling → fully mottled, speckled feather pattern

How to collect a feather sample
  1. Pluck 3 to 5 growing feathers from the chest or back. Pull them out, do not cut them.
  2. Check that the soft quill tip is attached to each one. That tip holds the DNA, a cut feather will not work.
  3. Put each bird's feathers in their own labelled paper envelope or a small ziplock.
  4. Mail the envelopes to us in a regular stamped envelope.

Takes about a minute per bird. No vet visit, and nothing ships to you first.

*Please do not choose this option 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 silkies that aren’t old enough to have real feathers yet.
