Automatic hydration mechanism The chicken water cup uses gravity and spring elasticity to automatically replenish water. When the water level inside the cup drops, the spring tension opens the water outlet to refill. When there is enough water, gravity closes the outlet to prevent overflow. This keeps water available for poultry at all times and saves you time and effort. Deepened design and double rubber ring protection The water cup is deepened to hold more water and to improve the closing action of the outlet. Each cup is equipped with double rubber rings to enhance leak resistance. As a result, the cup remains leakproof even if poultry pecks or bumps into it. Easy installation and flexible use Includes specialized opening tools for easy setup. Simply drill a hole about 2.5 inches from the bottom of the bucket to install the water cup. You can flexibly adjust the position and the number of perforations to meet different water needs.
