Thanks El Jeffe. . . .we want the Deer in we don't want the Cows or Goats. . .So. . . .3 stands of hot wire starting at about 12" and ending at 40". What the guys have said yes to is that Deer will have no issue dealing with a hot wire around feeders.

the electric will work for the livestock (if they are used to or get used to the electric and you provide a large enough shock (should have at least 3000 volts - 5-6000 is better; if not they will get thru and once they know there is a reward - your feed- for getting thru they will keep coming back). cows are pretty easy, but you may have some difficulty with the goats - they can be quite stubborn and tough to control (generally we recommend 5-7 strands for control (but again, good electric helps)
