DESIGNED FOR LONG TERM USE: The electric chicken wing opener is designed for long term use. No wiring is required and only 3 AA batteries (not included) are required for operation. The absence of complicated wiring reduces the risk of failure. The battery compartment is located on the surface of the drive system, eliminating the need to disassemble the coop to replace the batteries. [The new generation of cooperators have two basic modes: photosensitive mode and manual mode. The different modes work in tandem, for example the chicken coop door automatically opens at sunrise and closes at dusk without adjustment. [Protect your chickens]: the door opener closes the door of the poultry house reliably and provides sufficient protection against nocturnal predators (foxes, minks, etc.). The automatic chicken coop door is equipped with a protective device. When the door touches the hens, it stops automatically. You don't have to worry about hurting your lovely hens. WATERPROOF AND DURABLE Made of ABS, it is waterproof and resistant to high and low temperatures. Ideal for indoors and outdoors thanks to its waterproof case. Requires only 3 regular 1.5V batteries (not included) and can last up to 8 months; can also last up to 5 months when batteries are low.
