Butterfly Feeder is an Innovative New Concept. The Butterfly Feeder overcomes the deficiencies of traditional “pan type” feeders. It’s the only feeder that grows with your birds. Poultry producers can easily and cost effectively upgrade their existing “pan type” feeding system to Butterfly without having to install a complete new system. Butterfly Feeders will improve the health and productivity of your poultry. Wash down and cleaning takes 2 seconds of turning an Actuator Winch.
