Dominant Bl = Lavender?
Guest:
The gene that causes khaki, chocolate and fawn is called the dunn gene. Khaki (fawn) birds have two dunn genes (ID/ID) while chocolate birds have only one (ID/i+). It is incompletely dominate and dilutes both black and red/gold. It will dilute black more than red. It works just like blue genetically. Khaki (fawn) would be like splash and chocolate would be like blue.
If you were to have a bird that was heterozygous and carried the dunn gene (ID) and dominate white (I) you would have some real problems trying to figure out what was happening.

What do you think the bird in the photo is? Is it a chocolate/khaki?
Guest:
I do not know the pedigree of the birds in the picture therefore I will not make a guess at the phenotype of the bird. I gave the genetic information behind the phenotype in question.

John, I think your birds are very similar. Why did you stop working with yours? My splash/dunn do not have good quality of feather or lacing. In horses, we see some horses bleach quickly in the sun whereas others do not. I had thought this discoloration was bleaching. Which I do see in the hackels of the F1 father of these dunns. I\'ll attach a photo of him before molting.
I guess I should clarify: is it common for splashes to be varying shades? I have several of the \"white\" which i thought to be splash, and I have several of what now may be splash/dunn, and also several \"varying shades\" splash.
John:
You may find some black in a feather or two on a white bird. Of course it is not a good thing. Splash is white with \"splashes\" of varying shades of blue all over. The smoky (or whatever they truly are) also sometimes have a bit of \"splash\" to them. I still have a couple birds related to the smokys. One is a pullet that I\'m experimenting with by crossing a silver cock over her this year. The other is a 1/2 lavender d\'Anver (bantam) cockerel (see photo) that I\'m using on the LF lavender project. They could be smoky, dun or even dominate white/recessive white or ?.
