I'm going to be building a detachable chicken run out of PVC piping soon. It's not going to be anything fancy, just a 10x10x3ish run with hardware cloth around the outside of it. It just occurred to me, however, that hardware cloth may not be needed on the top of it, just the sides, which would allow me to use a somewhat weaker material? Your thoughts? Should I just use the sturdy hardware cloth all around it?
