I guess you are wanting a automatic feeder? We are in the process of buying some of the Stump Feeders.
www.stumpfeeder.com They hold 55 pounds of feed and are gravity fed. Some of my friends have bought the small mechnical feeders and had allot of problems with the timers.These stump feeders are fool proof unless someone wants it worse then we do.They appear to blend in with the surroundings well..I just thought I would mention these.
