I have a 4 wire electric fence and it is doing a good job keeping the goats in so far. However, we are very dry and I am worried about getting a good ground. I presently have the wire at 8", 16", 24" and 32 ".

More than keeping the goats in, I am thinking of keeping the coyotes out. Or at least increasing it's effectiveness by adding a ground wire in the middle. (i.e. 8" 14" 20"...Ground, 28" and 36").

Any thoughts?
