I eat plenty of meat and fat from pastured animals and am happy getting my omega-3's that way. But, the local Mexican grocery store has irresistible beef feet, chicken feet, sheep skulls, and other goodies that make really yummy broth. I'm guessing that this stuff doesn't come from happy animals that grazed but these goodies are not easy for me to find from pastured animals.

How worried should I be about making broth from these less-than-paleo-perfect parts? I really don't want to break my bone broth addiction.
