So I just rehab'edan old 4 wheel farm trailer (think hay wagon). I am told there may be bears in the area, so I ordered a 10kv battery powered fence charger. I am gonna put 10 or 12 hives on it for ease of movement. My deck is 12' x 7' and I plan to set the hives back from the edge about 6". My thought is to attach the fence to the trailer, with a slanted corner post on each corner. Is this a bad idea for some reason? Also how many wires should I put and how far apart?
