Wow! Wish I had read this before we had goats! We've gone through just about every fencing option available! We have one very stubborn doe (Alpine) with very large horns that curve back. She has learned to go through or break down every fence! Her newest trick was to lift up the electric fence with her horns, which don't seem to directly conduct electricity, and slip through the fence before the wire can come back and touch her in the rear end! Now we have 8 strands of electric wire pretty closely placed. Sometimes she still decides "the grass is greener..." and just walk through it, taking the shocks. Next time, I'm trying the peanut butter/tin foil trick!
