chickenbutt I am in northern Florida and I use 2 x 4 inch welded wire on my runs. I get it at Homedepot for like 76.00 for a 6' x 50' They have shorter rolls that are longer. I use that and then put a 2 foot high length of chicken wire on the inside of the run. This keeps anything from reaching in and since its on the inside they can't stretch it out to get in. We live adjecent to the wildlife management area and have coons,opossiums,weasels and much more nothing gets into the run.(it is also dug down 2 feet) Its juch cheaper than hardware cloth and just as effective.
