I'm building a coop and enclosed run in my suburban back yard and am debating with myself about the size mesh in the run. My biggest pest is likely to be rodents and I'd like to keep them out of the run. I've heard that a committed rat can get through anything larger than 1/4", but I just can't believe that. I'm wondering what size mesh do you use (I'm thinking hardware cloth or welded wire) and have you ever had rodents in your run. Could I get away with 1X1" hardware cloth?
