Not available in Quebec. Made to work with the Little Giant hen hydrator, this four-pack of Little Giant poultry nipples can also transform a standard bucket or pipe into a watering station for your birds. These nipples are designed to be installed vertically to allow your flock to get their fill of water, while keeping it clean and free of disease. Each nipple may accommodate up to four birds. Designed for use with adult birds. Do not use in freezing temperatures.
