We do not own our home, we rent. I'm looking for ideas for a semi-portable run. Once it's set we won't be moving it around or anything. But since it's not our property I don't want to build a permanent fixture. My question is: Does anyone have ideas on how to construct a good sized run that would be stable, secure, and sturdy to keep the chickens in and predators out but would still be somewhat easy to tear down in case we ever have to move? More specifically, most bury fencing under the frame of the run to keep digging animals at bay. I want to prevent the digging but don't want to dig huge ruts on my landlord's land. Nor do I want to spend a great deal of money to do this. For the fencing part of the run I plan to use either dog kennel frames with 1/2x1" 16 gauge wire or build the panels with 2x4s. Same frame work for the top. Secured with screws that can easily be taken apart later if need be. Easy to expand and easy to move. Win Win. But I can't seem to figure out a digging preventing system. LOL... I know, lots of restrictions here. Any ideas?
