You can mix all crested breeds like Altsteirer (Styrian), Sulmtalers, Sombor Chicken, and Polands, of course.
They are all closely related to the Polish Dworska. In German they were called Polnische Prachthühner in ancient times; and when they were kept and shipped via Hamburg to Great Britain (because Poland belonged a long time to the German kingdom), they were called Hamburger Prachthühner. This fact has led to misunderstandings about the origin of the crestless and "real" Hamburgs with some artists/authors (like Albin, Buffon, Moubray, and others) until the middle of the 19th century. They thought that the ancestors of the Hamburgs had been crested birds.
Today, it is known that the ancestors of this better known Hamburgs, which were called every day layer in earlier times, were actually derived from the Dutch breed Assendelfters.
If you prefer rose combs, take Wyandottes, Dominiques, or Redcaps.
