The inspectors here on the Island won't allow the processor to give us back the feet so consider them a valuable commodity. They make *incredibly gelatinized* chicken broth. I brought some I made to a friend once and she was skeptical at first and then every time I visited it was, "can you bring me more?" What I've read since suggests that adding some quality greenery when making it really improves the nutritional value, but if I don't get that far I consider that whatever I use it in will likely have veggies added then.
I did not need 300+ chicken feet.
