Has anyone done it? As I continue to plan and plan and plan for chickens this spring, I am still brainstorming for the best and cheapest coop available to me. We've got a broken down old trailer on the property... I was wondering if it would be worth it to gut it and use it as a chicken house. Would any of the insulation or materials used in there be dangerous/ toxic to chickens? Thanks for any links, advice or what-have-you.
