The e-alleles have more to do with coloration rather than specific breed. The five most accepted e-alleles produce distinct chick down coloration in their pur form. E (extended black) are the penguin colored chicks, ER (birchen) tend toward dark down often with brown heads, eWh (Wheaten) are cream colored, e+ (wild type) are the distinct chipmunk stripe, and eb are dark brown often with broken/faint chipmunk strips. As adults (and to some extent as chicks) can vary quite a bit due to other color genes. Over at The Coop's genetics forum there is a section of chick coloration photos which shows the basics as well as the great variations possible. As for D'uccles, as you thought, being partridge based, they are most likely eb based as partridge is the more common of the eb colorations. Dave
