I tend to ignore chick down but my guess is the e-allele they are based on.
The dark ones could be Birchen-based E^R (or extended black E) and the light ones could be partridge-based e^b, maybe heterozygote (mixed).
Also Columbian Co and Dark brown Db could have effect in this stage.
My silver spangled hamburghs have a similar layout as chicks.
They are Birchen based plus Db (and more).
