You have made me miss having goats. It is a shame but they will damage trees. I'm not sure there has been a fence made that will hold a goat that wants to roam. Story: We had a kid born that from the get go thought she was a lap dog. Now, holding a very young kid on your lap is not a problem but in a few months time they are too big for the lap. This kid was very affectionate and loved attention and curling up in my lap. By the time she was four months old she had to stay down. When she was about six months old I was sitting outside in a lawn chair. The goat was maybe 25 - 30 feet away when I noticed she was looking at me...cocking her head one side to the other. Suddenly she came running toward me and about 12 feet away I realized her intention. But goats are fast. At about six feet she made a flying leap to get in my lap. When she landed she hit my chest, the chair went over backward, she flew over my head, came up with a very indignant bleat and never tried that again.
