Our flock is housed in a modified horse stall in one of our barns. It has worked well, but we are a bit sick of the chicken mess throughout the barn aisle (the stall door has so far been their only entery/exit point) so we are going to add a pop door in the back wall of the barn. If we leave next boxes where they are currently, the space for the pop door will be beneath the nest boxes. This makes a guillotine-style door impractical. Does anyone have experience with hinged pop (or other fancy solutions) door designs that have worked well for them? Security and ease of use are my goals. If you have an example in the coop photos just send me to the correct photos. I have been looking over these as a group, but my free time is quite limited so I can't look at all of them in my search for just pop doors!
