Took the words right out of my mouth, or from my pen, or from my keyboard.
An electric fence is relatively cheap and very effective to keep them corralled. More goats is better than just a few.
Electric fence and goats. The words simply do not go together..... If there is a hole in a fence, a goat will find a way... electricity or not :)
They also can be farmed for milk and cheese. Very healthful. Might find a local farm wife or foodie who wants to be the caretaker and make the profit from milking.
