Make sure the feeder is 12 volt and shoots in one direction. Add a metal cone if it is at all flat on the bottom, and add a wire auger that goes from the fins on the plate up inside the tube to the feed. I drilled holes in the fins on the plate then added a piece of wire thru the holes and in an inverted V to keep the grain loose . This wire will keep the feed loose after a blowing rain or heavy moisture period. I also put it on legs in the water with a half round gutter extended over the water. That way it will feed in to the water even as the water recedes. A fence around the same feeder keeps cattle away and helps support the gutter or trough.
