Designed for long-term use: The electric chicken shutter door opener is designed for long-term use. There are no wires or cables and the opener operates on 3 AA batteries (batteries not included). The absence of complicated wiring means the risk of failure is low. The battery compartment is located on the face of the drive system and there is no need to disassemble the coop to replace the batteries. Multi-scene and multi-mode operation: the next generation of Cooperative Water Boilers has two basic modes: photosensitive and manual. The different modes work in synergy, for example the chicken coop door opens automatically at sunrise and automatically closes at dusk, without adjustment. Protect your chickens: the chicken coop door opener reliably closes and provides sufficient protection against predators (foxes, minks, etc.) at night. The automatic chicken door is equipped with a protective device. It stops automatically when the door comes into contact with the chickens. You don't have to worry about hurting your cute little chickens. Waterproof and durable Made of ABS material, it is waterproof and resistant to high and low temperatures. As it comes in a waterproof case, it is perfect for indoor and outdoor use. Only 3 regular 1.5V batteries (not included) are required to provide 8 months of battery life. No complicated wiring is required and the indicator light continues to flash to indicate a low battery alarm when the battery level drops below 20%.
