AFChick is right on these:
Sizzle- barbed (hard) feathered in either smooth or curly
Frilkie- non-barbed (soft) feathered curly (This is just a nickname for a frizzled Silkie)
However, on the FB Sizzle Chat, a "Shizzle" is a Showgirl (NN) with barbed (hard) feathers & can be smooth or frizzled (frizzle Shizzle) - try saying that 10 times really fast.
A Showgirl with frizzled silkied feathers is a frizzle Showgirl or frizzle Naked Neck Silkie. There's no nickname for this one. Hmmm...maybe a "Frigirl"? lol
Thank you for the clarification on the "Shizzle", Country- I own PLENTY of sizzles but no "shizzles" sooo lol (their necks bother me being bare.. must be some sort of latent phobia
"Frigirl" hmm not bad .. kinda like ladybug for both genders (another reason showgirls bother me lol)
