Details: Watch the video below on how they work. Easy installation. Turn any container into a poultry waterer - Use a 3/8" drill bit to create holes, 1" above the base of the bucket or use 5/16ID+7/16OD tube - Not recommended for winter use when temperatures drop below freezing. We recommend swapping these cups for RentACoop's horizontal nipples as they use the same hole and do not freeze when used with a bucket heater.
