Is that chicken really free range?

 So after the silly article in NPR, a lot of people simply said that paleo is definitely not about grain-fed meat. But I find a lot of people who purchase "alternative" products are eating grain-fed meat without even knowing it, simply because it's pretty hard to do commercially viable chicken or pork without it. I and others have worked on models, but they aren't coming to a store near you anytime soon.
