LOL, us too. Never saw the need for a pop door. We open the little door to the attached run and close every single night. We also always lock the hardware cloth covered door to the run with a carabiner. Nothing could get in, or ever has. I feel better anyway checking on them and shutting little door. Personally, I got in the habit of cleaning the coop every single AM of the year. It only takes 15-20 min or so and I never have any poop, smell, etc. It's worth it to do that and avoid the rank ones that only get cleaned every few months!
