We rescued this chick as a hatchling, with no idea on breed. Now that he is several weeks old his comb is coming in and it's BLACK! I've only heard of a couple breeds with that and they were rare. Any idea what this guy is? The inside of his mouth is white, his legs are black. His only other characteristics are he still has a white patch of down under his chin and his wings are crazy long. They wrap around under his tail and touch.
