Something to consider, i have heard many people say they have normals that have the markers and that these animals are not hets. While this may be true, you really dont know if your "normals" are not hets unless you breed them to pied stock to find out.

There have been a few people who have produced surprise pieds from import females that have markers.

I have two females that have markers, and produce babies with markers. I have one older female with markers , who's duaghter with markers just gave me a clutch , some of wich had the markers, clearly passing the markers along for three generations, Now if onky I would not have sold my pied!
