I build a duck/chicken feeder for my animals. The first type used a 5 gallon bucket with digital timer. My current model uses a 55 gallon drum (food grade). The motor is still mounted below while the timer is mounted on the side for easy access. A 6″ metal air duck directs the feed to fall down into a gravity feeder. Holding over 200 lbs of feed. It provides many days of worry free feedings.
