I was wondering if anyone could give me some advice about electric fence wire. I am going to fence in 18 acres in 3 acre blocks to rotate beef cow heifers and a bull to raise calves. I plan to use 4 wires but I am not sure if I should use 12 1/2 gauge gal. or 14 gauge gal. I want to do it right the first time but I don't want to use a heavier wire if it's not needed. I plan to drive the 6''-8'' x 8' corner post in 44'' and have 52'' above ground. I'm in NC and clay is down maybe 16'' or less in my area so I was thinking if I used the 14 gauge I would not brace the corners. Any advice would be greatly appreciated.
