best i can guess is yeah, the chickens do grub about, but their primary feed is corn and soy, i.e.: vegetarian.
i finally found a regular source for all-the-way pastured, organic hens, and am thrilled. i had been making do with the cage-free, organic omega-3 eggs too. better than a battery hen's eggs, by far.
have you tried mail-order for pastured pork? or looked into meat csa's? having watched portlandia, i'd think you'd have no trouble finding that stuff out thatta way. :0 (yeah! i know, different state, but to a crusty new englander, same mindset, tyvm.)
i'd be a vegetarian if bacon grew on trees.
