The invention provides a stem for a watering nipple for use in supplying water to poultry. The stem is hollow and formed of coiled material in a manner similar to that of a coiled spring such that the stem has a number of turns and minuscule gaps provided between adjacent turns. Upon actuation of the nipple, a water-tight seal is broken such that a majority of the water is directed to flow within the stem and directly into the mouth of the poultry. Some water, though, will flow along the outer surface of the stem. This water will either be drawn into the stem through the minuscule gaps, such that it will flow directly into the poultry's mouth, or this water will adhere to the outer surfaces of the stem to attract poultry and allow poultry to drink the water thereon.
