I think Rockin' Rooster Ranch in Arizona used to have them (maybe still do). I can't find a website for them, but other contact info is on the Feathersite hatchery page: http://www.feathersite.com/Poultry/BRKHatcheries.html
There is a place called the Fancy Chick in Wakeman Ohio....Art Gisbrecht who will be stocking them in spring 2012. They look awesome, plus the blue egg is always fun!
