Preparing for winter was a concern from the onset of setting up my back yard coop design. I simply placed the entire coop on a trailer so I can move it to any desired location, be it in between buildings to reduce wind chill, or into a shed in extreme conditions. Then be able to relocate it back after the threat has passed. This also has proven handy when going on vacation, just hook up to the coop and drop it off at the neighbors who will care for the chickens while away.
