My run is chain link dog run wrapped in 1/2 inch hardware cloth, top covered in hardware cloth, and 2-3 foot wide apron surrounding the entire perimeter. The coop has hardware cloth over ventilation under the eaves, over the 2 windows, a 2-3 foot wide apron around the perimeter, covering the entire underside of the coop floor, and wrapped around the entire bottom 4 feet of the walls sandwiched between the frame and the outer walls. I have carabiner type door locks on the run gate, the coop people door, 2 on each window, 2 on the pop door. This spring I need to make some serious repairs to the hardware cloth covering over the top of the run. We just had 2 feet of snow and ice and are about to get 2 more storms this weekend with significant snow. The present snow is causing the hardware cloth to sag deeply and hasn’t melted but rather turned into a Boulder of ice. A tiny birdie has gotten in, the first intruder in 3.5 years. I just can’t do anything about it until the ice boulder melts. Then I have plans for improved supports.
