So with the recent damage to my coop, I am looking at making some spring upgrades. I have a 10x10 galvenized steel dog kennel that I want to turn into the run, much like this one:
I'm adding hardwire cloth, of course, but my question is, what would be the best way to protect the bottom. I can't bury it 18" down, and adding a concrete "floor" is not feasable at this point. So, any other suggestions to keep the kids safe?
