I have relatives that eat chicken feet and make broth out of whatever is leftover (bones and YES chicken FEET). I still find it a bit odd. Can't bring myself to eat chicken feet though I guess I should try making my own broth with the feet in it as well. As far as the head. That's gross! ha ha
Heads and feet also make good dog food (we rawfeed) but I sometimes keep a couple of the feet back for my stock like everyone else has mentioned.
My dog Dusti is also known for "aging" her meat a little bit especially when it comes to the heads, but I think it's about 3 days tops
Never!! More power to the rest of you ~ I am so happy that you have the best broth around. I think I'll stick to my plain jane broth using, the leg portions.
