I'm wondering about using the plastic 1/2" hardware cloth. I haven't seen anywhere that anyone has used it, so it must not be recommended. But it is SO much cheaper than the metal! We have used it before for other things and it seems to hold up (not deteriorate) fairly well. Why would it not be a good idea to use the plastic?? Thanks! I have 8 chix very anxious to move out to the new coop / run, so the sooner that cloth is up the better!!
