"Showgirls are a work in progress.
The goal is to create a bantam bird with 5, evenly spaced toes, compact Silkie body type and Silkie soft feathering, dark beaks, even purplish-black skin, a walnut comb, dark eyes, large Silkie crests, naked necks (with bowties, beards, both, or neither), and good mothering abilities.
Breeders begin by crossing bantam Transylvanian Naked Necks with high quality Silkies in order to secure the dominant, expressed Naked Neck gene. The first generation from this cross doesn't look much like a Showgirl at all, but does have a naked neck. From there, breeders cross these hybrids back to high quality Silkies in order to improve type conformation. They begin to look like presentable Showgirls by about F7 or F8, if the breeder is lucky."
Just try to find the very best silkie you can find. Read a lot about silkie conformation, and you'll be fine.
