In the past, trough, bell and cup waterers were the primary types of waterers used in broiler production. Currently, almost all broiler houses are equipped with nipple waterers. Nipple waterers provide several advantages over other types of waterers. They reduce water wastage, litter caking and condemnations and they keep water cleaner. Broilers obtain water from nipple waterers by pecking the nipple, in turn activating a pin that releases water into the bird's mouth.
