A feeder cover for a paintball loader with fins that allow paintballs to enter, but not exit, the paintball loader. The feeder cover can easily clip in and out of a spring-loaded hinge of the paintball loader. Additionally, the feeder cover has an open and closed position. When the feeder cover is in the closed position, the feeder cover covers an opening of the paintball loader. The feeder cover has an opening that is partially blocked by fins. The fins of the feeder cover may have spring-loaded hinges that allow the fins to go from a closed position to an open position. Paintballs traveling into the paintball loader may push the fins from the closed position to the open position. The fins are individually removable and replaceable.
