Can raccoons get through or break through 2"x4" welded fencing? I know that it is advised to have smaller such as 1/2" Hardware cloth on the lower tier because coons can reach through and grab, but I am wondering about there ability to climb and then break through 2"x4" fencing higher up. I am going to be leaving for 3 days and my birds need access to their 6'x9' run for food and water. It is locked down tight with 1/2" cloth and 2"x4" cloth higher up. Roof paneling on top. All eaves covered... My other younger birds are in a larger new coop with food and water and will stay in there for the 3 days. Their run is not secure. What can a coon do?
