Abstract
A feeder is provided for animals selected from domestic pets, cage birds, chickens, fish and wild birds. The feeder has a hopper to hold a supply of dry feed. A chamber receives feed by gravity from a lower portion of the hopper, and has a discharge outlet at one axial end of the chamber. A passage is defined from and includes the chamber and extends to an opening at the distal end of the discharge outlet for discharge of feed from the feeder. An auger is mounted for rotation about an axis within the chamber. The auger is adapted as it rotates to move feed along the passage to be discharged at the distal end of the discharge outlet. A shutter is adapted to occlude the passage and is provided within the discharge outlet. The shutter is coupled to and rotates with the auger.
