Nice. However the bigger problem for me is the mechanics. What motor do you use? Actually I think you also need some gear. We and many other people we know are using the Kerbl (not related to KSP) chicken coop door which is quite expensive (around 120 Euro). https://d3w207ykk8w4lq.cloudfront.net/public/thumbnail/33/a3/95/1678397711/kerbl-huehnerklappe-automatische-huehnertuer-5_1920x1920.jpg__C3.webp https://d3w207ykk8w4lq.cloudfront.net/public/thumbnail/33/a3... You can see in the image it uses quite intricate mechanics with a lever and a spring. It's also supposed to detect a stuck chicken, however that has never happened to us (or we wouldn't have noticed because the Kerbl has silently resolved the problem).
