I was wondering if anyone has plans for how to make a chicken door that slides to the side to open and close, and somehow locks. In the past I've always done the chicken door with a rope and spring hinges, and then if I want to lock it, I have to enter the chicken run and put a clip through some latch hardware. I would like to open and close these new chicken doors on the three coops I am building with a bar that sticks out of the fencing and then somehow turns to lock the door into place. the door will be right next to the side of the exterior fence. This way, I would not have to hurdle over all the interior fences that separate my little breeding coops, every time I need to let the chickens out or close them up at night. Have you done something similar in your coop, and have photos you could share? I'm sure I could figure something out but I'd rather not reinvent the wheel if possible.
