I have my coop build. I have my dog kennel run assembled. I have purchased the roofing material for the run but haven't put it on yet. And now I am wondering... should the coop itself sit outside of the run - with a little hole cut in the kennel that matches the pop door so they have access? Or should it sit inside the run? I have only 3 chickens. The coop is small. The run is 50 square feet. Opinions? Thanks!
