I'm trying to get one of my pasture fences good enough to let the cows back there, it has old field fence with one strand of barbed wire on top. Some areas are pushed down pretty bad by the deer, others not as bad. Originally I was going to add in t posts to the bad areas to pull them up and replace all rotten wood braces but now I'm thinking adding a couple strands of barbed wire in front of the bad areas could be cheaper, and still fix the rotten braces of course. It's about 4,500ft all the way around so I have a lot of work ahead of me! Any thoughts? Or tips?
