I found 1x2 wire but it is $109 for a 4'x100' roll and the 2x4 welded wire is $54. This coop has to keep lots of stray dogs out and racoons etc. so it has to be strong. Is it ok to use 2x4 or is the 1x2 better? If I have to spend the money to keep them safe I will if I have to. I think I will run a hot wire around it too.
