Abstract
A watering cup especially useful for watering chickens having a first contact actuated valve for admitting water which first valve bears against a second interior valve and holds the second valve open. The first valve can be removed for cleaning and inspection without the necessity of shutting down the water pressure since removal of the first valve closes the second valve and prevents leakage.
