I built a new coop/run today to house more chickens and we don't close the coop off at night from the run so I have to have animal proof fencing. On my old coop, I was using this fencing, but am going to sell that coop. http://www.doitbest.com/Utility+Fence-Do+it+Best-model-700668-doitbest-sku-700668.dib I am trying to find something cheaper to use this time since the run is bigger. I have been using this fencing for a year and have not had any problems, but need a cheaper way. If I use the 48" wide stuff they only sell it in 25' rolls and I need 30' so I would have to buy 2 rolls that is out of the question. I am not sure if I could use the 2x4 or I found 2x3 50' roll for 43.99. I just want to make sure a predator could not squeeze in there and go up in the coop and eat the chickens at night.
