sansheng 24Pack Chicken Waterer Cups,Poultry Water Cups,Automatic Poultry Waterer for DIY Poultry Quail Duck Chicken Bird Drinker;

Fully automatic - The glass has a yellow trigger that will attract chickens to peck it. When the chickens peck the Yellow trigger, the valve automatically releases water into the orange plastic cup to provide them with water. No leak - the cup will not release water until the chicken pecks the Yellow trigger and only releases enough water for the chickens to eat. It will not waste or overflow the water in the cup because of triggering the lock and release function. Easy to clean and install - Drinking cups can be easily installed by wearing them on PVC pipes or even containers such as barrels. If you do not install a PVC base to install drinking cups, you only need to drill a 3/8"hole. To clean the cup, you can easily remove or disconnect the cup from the drinker's line by turning the Orange Cup to the left and pulling it down.
