Since they are attempting to make a breed - writing standards etc. They're calling them Sizzles because some are curly like a frizzle, some are smooth, some are a curled silkie they call frilkies. But they have the many toes, dark skin, bearded or non, and top knots.
I got four sizzles, three smooth, and a frilkie in my batch. Including a very nice sizzle cockeral in splash. A nice black, a nice blue and a mottling grey sizzle - still changing color on a day by day basis. A blue with a red head and wing bows - smooth(sc). A black smooth with angel wings and some white on her feet, and the blue frilkie who is still feathering in albeit sloooowwwwly.
Sizzles are fun but a tad complicated LOL.
