my setup is a little different. the coops are attached to the runs and I don't close interior doors anymore, so if it the runs are penetrated, everyone is at risk, but I covered and skirted everything with hardware cloth, placed huge shale paving stones on top of the hw cloth that lines the ground to keep diggers out and chunks of maple tree trunk on top of the stones. nothing has ever been disturbed in the slightest. the runs all have roosts in them as well as the attached coops. but no one sleeps in the coops, or hardly anyone, during the warmer months especially. they sleep on the roosts in their pens. they have feed and water at all times, so when they wake before the crack of dawn, they aren't in small spaces, they have access to everything. currently, I'm running about 6-8 square feet per bird, depending on the pen. I have room for more, but like the fact that everyone has lots of space, I don't have bad behavior issues from crowding... I'm out early to bring more feed for breakfast, but they always have some left over from the night before... when I get home from work, I open the pen doors and let them into the yard. they forage like crazy, my other pets haven't had ticks or anything since we got chickens, and I have no problems with rodents now that I am down to one ancient female kitty and 2 lazy males... the chickens are the best pest control ever!
so, no pop doors here, and I don't have to worry about letting them out. just locking the human doors at the end of the day.
