Abstract
A drinker device for foul and stock provides a constant water supply in a cup by means of a valve controlled by a free floating ball actuator. The ball can be readily moved by the foul or animal to access the drinking water without actuating the valve controlling the water supply until the water level drops to an undesirable level. The device also provides convenient height adjustment mechanism and a quick unit replacement feature.
