Never been able to get a hold of either breed. Chanteclers are fabulous cold weather birds, but I've only heard of one person in my state that raises them. They're also a dual purpose, and I'm wanting to focus more on laying, lightweight breeds. Spitzhaubens are also fabulous, lightweight birds but the crest isn't something I want, and I know of one person who tried them on in my state (and she got out of them).
I do have a Polish, and he's pretty close to a Spitzhauben. Really like his demeanor, build and carriage.
I do have a chunk of dual purpose blood in already from the Brahmas, RIR, and Sussex/Orp. EE, OE, Breda and Leghorns are all more laying really than even dual purpose. Not sure about Sumatra but the line I worked with seemed more layer than dual purpose.
