We are busy designing our first chicken coop. We bought the Garden Coop Plans from My Pet Chicken. Okay, we are doing quite a few modifications. One modification was to make an access panel/door on an outside wall for easy cleanout. The cleanout door on the Garden Coop is designed as being on the inside of the coop run. Now it just so happens that the side where we want to place the clean-out door is on the side that gets hit by the rain & strong winds in the winter. To protect the chickens from the rain & wind we are going to plywood in that whole side from the top of the run to the bottom. We are wondering the best way to make that door weather tight. Any ideas or recommendations? We do not have construction experience but my husband is very detail oriented. The coop will go on a hillside so easy access is limited to only two sides. We are going to put the nest box on one accessible side and the cleanout door on the other side.
