I am planning to provide as much of a Fort Knox of a 20 x 30 ft. run for my chickens that I can afford. Part of my plan, for those climbing predators, is to have 3 strands of electric wire running around the entire perimeter. I was planning one strand at ground level, another 1/2-way up (at 3 feet), and the third strand along the top. With, say, 2 inch insulators to hold the wire off the actual fence itself. Do the 3 levels of wire sound about right? (vs. 3 strands at the top only......) or is there a better way? Also, do 2 inch insulators sound right? Any electric fence advice for this application would be appreciated. (I plan on a 14 volt (big zap!) charger to power the wire............and initially "baiting" the fence with bacon........................so those who might be drawn-in by the smell, and who might venture to bite down on the bacon, would, um, NEVER think to do "that" again!!!!) Thanks in advance!
