After spending over a week designing drawing up plans, and pricing materials for my wooden run, I found a 10' by 10' dog kennel on CL today for $75. I'm thrilled! I was planning to put 1/2" hardware cloth 2' or 3' up, but does it go on the inside or the outside or the chainlink? I will also lay a hardware cloth apron - how wide should that be? I notice many people are using chicken wire on the inside of the chainlink. This would certainly be cheaper, but am I risking the security of my girls? I also plan on using 2 x 4 welded wire as a roof, probably with some 2 x 4s run across for support, and perhaps covering that with either tarps or corrugated PVC. I am getting my first chickens tomorrow, so I'd appreciate your advice.
