This automatic hanging poultry feeder is ideal for a variety of birds including chickens, ducks, and turkeys. Constructed from high-density, BPA free, polyethylene plastic that is semi-opaque, so you can easily see the water level inside the container for convenient refilling and cleaning. This feeder uses three adjustable metal clips to hold the pan in place to the tube, allowing for five different feed flow rates. The different flow rates allow for customized feeding levels for the birds. The sturdy construction of the feeder and metal handle bracket allows for easy transport and ensures long-lasting use.
