PM me, I'm not very far from you and you can come see my chicken setup and bring home some eggs. I do not vaccinate or use medicated feeds as my whole goal is happy, healthy chickens with non-chemical filled eggs.
Mine free-range so absolutely none of the issues that come with overcrowding. I do not buy organic feed but because mine free-range, they don't eat a ton of feed. It's always available but unless it's snowing and they hole up in their coop for days on end, it's eaten pretty slowly.
