The farm I recently purchased thankfully already has perimeter fencing. All 50 acres is fenced with woven wire and 1 strand of barbed wire on top. For the most part the fencing is in OK shape. But in some places, the top of the woven wire is loose. What is the best way to fix this? I'm a fencing rookie. And some other areas the woven wire is pushed down from the deer. Any help is appreciated!!
