Our line of proteins are all fit for human consumption but do vary in how they are raised. Grade A is the standard meat you get from Safeway and other supermarkets which makes no mention of how the animals were raised. Our Naturals lines are from animals raised without growth hormones, antibiotics, or animal by-products. They vary between free-run and free-range. Free-run animals are provided slightly larger square footage and have access to light (not necessarily outdoors) whereas free-range animals have a small area that the animals can get to outside. Free-run and free-range relates mostly to chickens and turkeys. Larger animals are outside most of the time due to their sheer size and temperament.
