Abstract: A poultry feed restraint is disclosed and is adapted to control the eating habits of a selected bird. The restraint comprises an elongated, resilient body that penetrates the beak of the bird. The restraint is inserted through the bird's nostrils or nares to a midpoint. Then the restraint is rotated from the insertion position to a deployed position. A pair of opposing ramps rest upon the exterior of the beak to secure the restraint. A groove defined between the ramps facilitates the rotary movement of the restraint. The restraint prevents the bird from inserting its head into a feeder equipped with a guard or grill. The restraint may be used as part of a system to effectively control the consumption of feed by selected birds. In the system, a feeder with a grill disposed over its top is used. The grill has a predetermined access gap between its bars so that the unselected birds may eat freely from it.
