Our run is covered with plastic mesh "bird netting". After hours of freezing rain, followed by sleet and then snow, the cover to our run is sagging pretty badly. It has wires crossing it to help hold it up, but I'm guessing they can only stand so much weight. There are icicles hanging down, with clumps of snow-covered ice on top. We tried knocking down the ice by using a hard flat item to break it off, but the clumps are not breaking up enough and they're too big to fall through. Ugh. Anyone who has dealt with this before? Not sure how to proceed and worried we are going to have to re-cover it.
