If FORAGE is the word(not sure). Have a customer that is looking for pasture fed ONLY chickens(for eggs) as she is striving for a grain free diet(which I respect as she is slender,very healthy) but before I go online trying to research this wondered if anyone had FACTS about doing such a thing. And you would obviously have to feed them SOMETHING in the winter(snow) or I envision my domestic chickens starving to death. Do they sell grass based diets? I know I hear stories of "wild" chickens that my grandma used to catch and cook but it doesn't seem like the majority of chickens born would make it.
