All I know I have found out through other parties. I'm sure that if someone builds enough of their own stock to offer some of them for sale, they will do so. From what I can tell, there were some in Germany, but they died out. They do not do well outside of their homeland. They might even have some specific nutritional needs that are hard to meet in addition to their cold intolerance. The Ga Dong Tao is the breed pictured above and is a specialty meat chicken traditionally used for ceremony, weddings, etc.. The Ga Ho is a similar game breed. The feet get thicker with age. They are special, for sure, but I don't think many would be truly prepared to give them the care that they would need to remain viable.
