dreamrequest,
Chicken wire is pretty useless for coons and I suspect Fishers too. They can pull that stuff right off, or bend /chew a hole right through it! You are better off with welded wire, or better yet, hardware cloth with 1/2"x1/2" holes. Don't know about the Rubbermaid coop either. Does it have a metal or wooden floor? You might consider getting some electric fencing to add to the bottom and top of your run, strategically placed, that will stop them.
