I have some Spitzhauben chicks that are 2 weeks old and one that is 3 weeks old. They look totally different that yours. At least one of yours, maybe two, have single combs and they should not.
Mine are also fluent in German and I caught one goose stepping. (JK!)
Gimme a minute and I'll post a pic or two.
ET: Correct my incomplete thoughts. lol
