AUTOMATIC MODE: Our battery operated chicken door is equipped with a timer and LCD screen, with both automatic and manual modes. You can set the time for automatic door opening and closing on the LCD screen. And you can also manually open and close it at any time. WEATHER RESISTANCE:The chicken coop door is made of high-quality aluminium alloy material, which is robust and durable, and can work normally even in extreme rainy and snowy weather. Cold and heat resistant, can be used at temperatures from -9 C to 60C. Using mechanical anti-pinch technology, the door will jam and then automatically pop open after detecting an obstacle. After detecting the obstacle leaving, the door will automatically close again. This prevents chickens from getting injured and ensure their safety. BATTERY DRIVEN:The chicken coop door automatic opener is powered by batteries. With 3 AA batteries (not included),you can use it uninterrupted for up to half a year. When the battery level is too low, an indicator light will prompt you to replace the battery.
