Has anyone set up a dog kennel chicken run on a sloped area? (Everything's hilly down here so there isn't a better spot). What would be the easiest/cheapest way to do it? Gravel, wood, cinder blocks...? Dad wants to get rocks from the quarry and balance the kennel on them (no idea how that's going to work). I was thinking maybe I could dig out a trench to make it flat (I'm an archaeologist, so digging is my forte) but I might regret it once I start, since so much of our property is clay. It's not a huge slope, just gradual, going down to the ditch.
