People mixing breeds without understanding anything about genetics or how to breed for traits has caused a lot of issues. A decade ago getting decent showgirls was a problem because every Joe Smoe was crossing naked necks with silkies and calling them showgirls. Lots of hatchery stock used.
Then there is the issue of people coming up with fancy color names. The accepted APA colors have names. It's why the silkie 'porcelain' had to do a name change to blue cream. Porcelain is the lavender diluted mille fleur.
Calico is going to have an issue as it's been well established in a few breeds as mottled mille fleur. It's not an accepted APA color yet but those breeds are more likely to get it accepted with the breed club.
Heck even though splash is a double dilute of blue, it's only an accepted color in silkies. Even the Andalusians where the color came from don't accept it. Probably because blue is supposed to have a darker blue lacing around each feather.
Showing a partridge silkie you'll get a fault or disqualification for a black headed hen depending on the judge. Partridge is supposed to have a red head. So many have bred for the moorhead coloring its more common than the proper color. I think there is a breed that does call for it but not silkies.
The issue of split wing in silkies is what drives me nuts as it's inherited. Don't breed birds with that fault. Many who are just trying to make the biggest and fastest buck from chicks don't even check for disqualification like split wing before breeding. I always show wing pictures before selling birds along with foot and hock pictures.
