Thanks to heavy-duty galvanized steel and double-wall construction, Harris Farm’s 2-gallon poultry fountain provides a generous supply of cool water to promote intake for up to 51 poultry or game chicks. Constant water level maintained in the pan by vacuum, so no floats to get stuck or replaced. Model features: visible locking device, roost prevention tip, the inner tank has a brass valve with rubber sealing washer for positive shutoff.
