When in Hawaii I photographed a wild chicken (red jungle fowl). Our guide (Carl Berg) told us it was likely a cross-breed with domestic chickens, as the legs were not black. Take a look at the two together (opens a new browser window). I do not see any difference in the leg color, though I must admit that the print has a much more pleasing background than then asphalt road in my photo.
Red jungle fowl are widely spread on the Hawaiian Islands, and local people call them "dinner." Whether a "pure" red jungle fowl still exists on Hawaii is not certain. Having seen and photographed them myself, I must say that they are beautiful birds, and certainly look like the print shown in the comparison.
