Capsule Feeders are the innovative, problem-solving alternative to traditional tripod and gravity feeders. Capsule Feeders sit on the ground and use patented auger-driven technology to move corn from the bottom of the feeder to the top. This makes the Capsule Feeder the safest and easiest feeder to fill. When a tripod or gravity feeder is knocked down or ransacked by varmints, you lose the money you spent on the feeder and the corn.
