I have chicken wire surrounding my run, but the sides are 6 ft dog run fencing. The chicken wire runs over the dog run panels then across the top all the way to the coop to make a run cover. This last snow storm a couple days ago pulled the 2 x 4 that held the chicken wire right off the coop and the whole thing collapsed into the run. Any suggestions of how to make it more secure next time? I never thought the snow would be that heavy and not go through the wire.
