So, my coop is set, my chickens are happy and protected - since they are still growing up in the coop. Next step is the run. My sister lost most of her chickens to a mink that dug under her perimeter fencing. We have plenty of foxes and some coyotes here in upstate NY. Does anyone ever literally "box" in their run? That is put a layer of fencing right into the soil a few inches down as a "floor" layer and connect that to the fence walls? That way the predators can't dig up underneath or they would just hit more fencing. Seems like a logicial solution but I don't ever hear/see anyone mention it. Too much work? Not practical? Issues I haven't thought of? We will also be covering the top with some type of wire to keep the hawks out.
