Check out the family-owned and operated Happy Henhouse. We make advanced, user-friendly, durable chicken coop electric doors. The outdoor rated controller uses a modern design and unique components. The controller is powered by 4 AA batteries. It uses a robust gear motor that closes the door at night and opens in the morning, giving complete protection for your chickens. The highly adaptable controller uses a timer or light sensor to activate the motor, allowing you to choose when you want to open the coop door.
