No, Frizzles and Sizzles arent the same thing. A Sizzle is a Frizzle. Frizzle is just a term used to describe birds with feathers that turn towards their head. Sizzle is just a nick-name people use to describe a Frizzle Cochin and a Silkie Cross. What Jaynie has shared. You will get Frizzle and Smooth Sizzles and that is how you breed them. Just as any other Frizzle breed.
