I currently have 8 acres fenced and its split into 4 pastures. One is about 3.5 acres and gets very over grown. My neighbor has 12 Alpines that she has on about 1 acre. its been ate to the ground and I was thinking of asking her to let them stay in in the back pasture. Its only 47"-11-6 fence without any hot wires. is that enough to keep them in? on a side note the neighbor uses stock panels and no hot wire.
