I am looking up priced on "redman" welded wire in the 48x100 size........ what gauge 14/19 is best? Most important .... is 1x2 safer than 2x4.. can a coon or possum get into a 2x4 opening. Please help ASAP ....!!! I am building this weekend. What do you all use? I do not want anything to kill my chickens. I am making a 25x50 run and was thinking of putting the 1x2 welded wire on lower 4 feet and the higher 4 feet closer to the top using the 2x4 welded wire. What does anyone recommend? 1/2 inch hardware cloth is too expensive to put all around. On the top I am putting a vinyl coated 19 gauge wire with branches/palm leaves for shade. Its cheaper than metal roof.
