Lanae,
I can't really tell anything from the photo because it taken from the front. All I can say for sure is that it looks like it is on either Birchen Gene(ER)or extended black (E).
I'm going to e-mail you some old pictures I have that show mottling on first feathers and also some recessive white chick down. These pictures are in old word documents that wouldn't come up as images on the ACA web site.
