I used a 4 inch y section PVC junction with a cap stopper one side and a 5 foot length extension the other end with removable cap for filling purposes and it is mounted 12 inches off the ground no more spillage and no more worries with rodents, later on I put in a y section on the feeder tube and turned it in to a double tube feeder and lasts 3 weeks with my present 5 chooks I would put a photo in but do not know how yet.
