We are building our run for our 6 chicks and are going to do all sides including top and bottom in hardware cloth. My questions are: Do we use staples to install it? Do we put it on the inside of the wood frame or the outside? I was wondering if raccoons or possums can pry the wire mesh off the wood frame. If they can would it be easier for them if it was on the inside and they could push it out. Thanks for any help!!!
