Abstract
A trigger-type drinker for poultry and small animals including a water retaining disc at the free end of the trigger pin is disclosed. The disc is generally flat with an upturned lip around the perimeter thereof. A residual water drop or water leaking from the drinker runs down the trigger pin and collects on the disc, contained by the lip. The disc allows several drops of water to collect at the bottom of the pin. The increased amount of water on the pin assists in attracting birds to the drinker. When the bird actuates the drinker, the disc tilts toward the bird, thereby causing the water to run across the surface of the disc and into the bird's mouth. Thus, the disc assists in directing more water to the bird. Additionally, because the side of the disc farthest from the bird tilts upward as the bird actuates the drinker, it not only acts as a ramp for the water to flow downward toward the bird, but also acts as a retaining wall, preventing the water from flying off the opposite side of the pin Accordingly, the floor of the poultry house remains drier.
