I think silver partridge and grey are different from each other because of what the judge said. Seems like silver partridge would have penciling like a regular partridge. But I might be wrong? I would like it if they were both recognized.
Quote: If you look at some of the threads on the club forum, there was a discussion about the males and females not matching in either phenotype of genotype. Pretty sure Sigrid began that thread. Anyways, silver partridge is a duckwing pattern, and the standard for grey silkie males calls for a duckwing pattern. The standard for females is a crow wing pattern. Grey for other breeds (this is a separate listing in the standard) is a crow wing pattern. The only difference I could find between grey and birchen was that birchen calls for less breast lacing than does grey.
