WOW, there is so much misinformation on this thread. Allow me to clear things up please as I've gone to a lot of trouble to understand these terms.
Frizzle: a chicken of any breed with curly feathers, often found in cochins, polish & seramas.
Frazzle: A chicken of any breed with a double dose of curly feather genes which causes the feathers to be hard, sparse & overly curled.
Frilkie: A silkie or silkie feathered silkie cross with curly feathers.
Sizzle: Is a breed that is in the process of being established. It has full silkie characteristics except that it's feathers are hard, not silkied. They can come in frizzle or smooth.
Crossing a cochin with a silkie does not make a sizzle or if it does, it's a very low quality one. Many breeders in the US are going to a lot of trouble to produce a correct looking sizzle. It is more correct to call your birds silkie/cochin crosses unless you have at least most of the type/characteristics established.
Speakup4kids has got a lovely duo of sizzles. Most of the others are crosses that aren't typy enough to be sizzles yet.
