DIY Feeder Chute This feeder claims "no waste water, nothing". It eliminates loose seeds and husks. Your bird goes in to eat, leaving the husks and uneaten seeds in the compartment below! This newer large feeder needs to be mounted outside the cage, not inserted into the cage. Easily attaches to the birdcage with just one screw! It comes with a wooden perch that allows the bird to stand comfortably during feeding. 1. Separate the grain or seeds from the husk; 2. Collect the chaff in a small box at the bottom, keep the room clean, 3. The feeder can store seeds for half a month or a month or so, depending on the birds.
