Hi all, we had built our chicken run with cattle panels in a hoop style covered with a large tarp- has worked great until last night! I went out to feed and water this morning , and as I got to the chicken coop saw that the entire run had caved in - down the middle - with the weight of the snow sliding off of the coop roof. luckily no chickens were in there,as they were still locked up in the coop. DH went out and shoveled the snow out of the middle, and went inside to raise it up with his shoulders. he managed to get all of the panels raised back up, and braced landscape timbers down the middle of the run. it won't cave in now, but we wanted to let anyone who may have built a hoop style run out of cattle panels to make sure to support it down the middle.
