SUPREMO WATERER: Get a five gallon bucket, 8 to 10 feet of 3/4 inch pvc pipe, two elbows, a cap and a coupler, and away you go. Set a post outside the coop. Cut three pieces of pipe as shown. Drill a 1 inch hole in the bucket. You'll need a watertight fitting to connect the pipe to the bucket. Anyone at a full service hardware store can hook you up with what you need for this.
