I LOVE this idea! I wonder if with 3 openings on the bottom for feeders with a large garbage can, plastic of course. My concern is the lid doesn't seal completely on top... maybe that would be a good thing? inside the coop I'm thinking the natural heat of the fermenting process might be enough to keep it above freezing since it's such a large batch. Or that at least it won't freeze completely. I'm so excited to try this!
