As a fellow NE Ohio BYC'er, I can understand the strain on the roof as we have a solid base of 2-3 feet, not counting the drifts. I currently do not have a roof on my run, but after losing 2 girls in 4 days to fox and hawk, I'm looking into ways to roof the run once we have a thaw! My DH bought me a fencer, and we plan to run a couple of strands of electric wire to deter the fox and any coons that decide to try to get in. But we'll need a roof of some sort to deter that nasty hawk that got the last one around Christmas time. I want something stronger than the aviation/deer netting, and was leaning toward simple chicken wire (The run itself is welded wire). Seeing how the snow did not go through your net roofing, I wonder if we would have any better luck with the chicken wire? Flat roofs + snow = trouble....Would a gable roof built with wire work? Think the snow would shed off? Maybe both of us NE Ohioers will have some luck with roofing ideas!
