Abstract: A feeder assembly includes a feeder unit and an open top portable storage vessel defining an interior chamber. The feeder unit includes a feeder and a coupler securing the feeder to the vessel. The feeder defines a feed opening in communication with the interior chamber. The feeder includes a conveyance assembly in communication with the feed opening. The coupler is selectively secured to the feeder and independently selectively secured to the vessel, such that the coupler selectively secures the feeder to the vessel. The feeder unit facilitates dispensation of a material from the vessel. The method includes the steps of securing the vessel to the feeder, such that the feed opening is in communication with the interior chamber through the open top; collectively inverting the vessel and the feeder; and operating the feeder such that material from the vessel is dispensed by the feeder.
