POULTRY PRODUCTION 



For small chicks, a good form of watering utensil is shown 

 in Fig. 190. These work much the same as a self-feeding 

 hopper. The tank, A, is closed at the top and open at the 

 bottom. When it is filled and in place in the pan, B, the 

 water is given down only as fast as air is admitted to take 

 its place. The latter can occur only as the chicks drink 

 enough of the water in the pan surrounding the tank to 

 lower it below a small hole near the bottom of the tank.

This allows a small volume of air to be admitted and enough 

 water flows into the pan to bring the water level above the 

 hole, thereby preventing any further flow of water into 

 the pan. A tomato can and a pie tin will serve the same 

 purposes. 



This arrangement gives a constant supply of water and 

 prevents the chicks from getting into the water. It does 

 not preclude the scratching of litter and dirt into the pan
