After studying the post on this forum I decided against using the “Chicken Wire” for my run and went with the Hardware Cloth. Best decision ever! Has turned away squirrels, raccoons, crows, hawks, dogs and most recently a coyote. Most of these attempts on my hens were caught on a game camera but I set and watched a rat snake make several attempts on entry before I relocated him. If you have a new coop or run planned I recommend galvanized hardware cloth!
