I have an opportunity to purchase 2 rolls of 150' x 6', black vinyl coated, 1" hex pattern, 20-guage chicken wire for $100. One on-line site I looked at sells it for $160 per roll and would ship two rolls to me for nearly $430. So, I'm convinced it is a good deal from the price perspective. My question is about the utility of using 20 guage wire around the run. I guessing the only 'safe' place to use it would be as a roof covering for my 12' x 36' run. Even there I suspect it would be best to make it double thickness. I'm interested in hearing opinions about if this is a good purchase or would its 20 guage weakness leave me with a false sense of security and my chicks vulnerable. Thanks.
