No difference in color, just black skin. It's a little tougher than the regular commercial birds.If you brought that to the table and set it before me I'd be aghast! LOL!
Wow, interesting-looking birds. Is the meat any different than your average chicken? Also black??
Taste-wise, its unfair to say gamey, but its definitely full flavor. More like pheasant or even turkey. Tougher, as mentioned, though our yard-bird chickens growing up were tough and flavorful too since they were really free-range. They had a coup. But thats all.
Regarding the head (comb) and feet add tons of collagens to make a rich broth. Cooked fully, its soft like beef tendon in pho. I'll admit that it looks gross, but sooo tasty!
