A feeder bag includes a bag portion formed of a front panel and a rear panel. A lower flap is pivotally coupled to the front panel at a lower flap junction and is disposed proximate a bottom end of the bag portion. An upper flap is pivotally coupled to the front panel at an upper flap junction and is disposed above the lower flap. The upper and lower flaps include slots. A first side brace defines a first upper tab and a first lower tab, and a second side brace defines a second upper tab and a second lower tab. The tabs of the braces are received in the slots of the flaps to create a trough portion. The front panel of the bag portion defines at least one through hole disposed between the upper flap junction and the lower flap junction.
