Love this automatic chicken door. It took me a minute to navigate the directions but once I understood and I worked with it for a minute it work great. I kept es it on our back porch at first to make sure it worked and sure enough at sun up it opened and sun down it closed. Then my husband installed it on our chicken coop and that night we went to check on the chickens were in the coop and the door was shut. Then the next morning when we woke up the door was up and the chickens were out. I love not having to go out there anymore and put the chickens away and shut the door. It’s going to make going on vacation soooo easy. Thank you!
