On free range eggs, iI a watched a short interview where the free-range chickens aren't actually running around in a nice open area as we would like to think. They have these massive "barns" that have openings so the chickens can go outside if they like, but because there are thousands of chickens in the barn, it would take them ages to get from the middle of the barn to one of the openings. Also, as there is plenty feed inside the barn, the chickens have little to no reason to venture outside. The man on the video used the term "non-caged" as opposed to free-range.
