Hello, I've had your chicken door for four years now, and it's really been doing the job well for my flock of chickens and ducks. I've had no issues with it, other than a dead battery this year, and the occasional frozen poop chunk that stops the door from closing (it can get cold in Michigan!). Other than that, it's been a dream. I do protect the door from rain and ice and snow, though, which could hamper the door movement. It’s a door, not a snow shovel!
