Now pet owners have the freedom of waking up on their own time to their chickens frolicking peacefully outside! Thanks to the fully Automatic Chicken Coop Door Kits that ensure automated safety of the chickens with a heavy duty door that automatically opens and closes to keep predators away. The coop doors are managed by a weather-resistant controller that uses a robust gear motor and an adaptable automated light sensor or timer to open and close. Adjust the light sensor to the amount of sunlight needed to activate the controller, permitting the doors to open and close when you want during dawn and dusk.To know more you can visit us at : https://happy-henhouse.com/products/automatic-chicken-coop-door-opener-kit-light-sensor-battery-operated
