I ran 2 foot high chicken wire around the bottom of my welded wire fence and cable tied it so they don't stick their heads through and get them lopped off by predators.
Hmm good point about the snow accumulation, going to need to re think this.
We have also used aviary netting from Amazon - it has lasted years and does catch sticks and leaves, but it's worth it. Once a raccoon managed to get between the netting and fence on the outside of the fence (netting was wrapped around and attached about 1 foot below top of the chain link - "sewn" on with paracord). It was apparently crawling sideways along the fence looking for a way to get over the top when it became entangled in a wad of netting at the corner and suffocated. Someone from the USDA came and removed it and tested it for rabies (negative of course). The USDA will apparently remove and test any wild mammal that unexpectedly dies near livestock - even though chickens don't get rabies! That is the closest anything has gotten to breaching the netting. (A couple of possums have gotten in when a gate was inadvertently left open. But they were apparently after food and maybe eggs and didn't harm the chickens, just stirred them up.) Once when the netting was off for some reason during the winter, a hawk killed one of the chickens, so I definitely recommend covering the run. (Our chickens have access to a larger fenced yard that is not covered, but they run to corners or under a tree when they see a hawk shadow in the daytime.) [ We're in north central WV about 70 miles south of Pittsburgh, PA and live in a suburban neighborhood that allows small flocks. We share the flock with a next door neighbor - a great arrangement for many reasons!]
We probably got the same snow storm, I was out with a broom also!
