Hi, this is my first coop and run. my coop is a solid box, with plenty air holes, a padlocked side i can open to access the coop, and on a platform. i think its secure, if you see something i don't, let me know. But my main concern is my run. I have a run that is an 8'X8' wooden frame, with chicken wire secured on the top and sides, there is a hole for the door of the coop that wasn't sealed together, but I am going to frame the wire between the coop and the run. What I worry about with the run, how to stop predators from burrowing into the run. Would adding chicken wire to the bottom of the frame be harmful for the chickens if I cover it with soil, hay, wood chips etc. Or would apron-ing chicken wire around the outside of the coop work just as well? Burying them (deeply) isn't an option at the moment because where I am, its winter and the ground is too solid to dig into. Attached is a picture, thanks! And again, I am adding a door to the coop and framing the wire from the coop to the run.
