For about 3 summers now I have been keeping goats behind a electric fence. It has done well at keeping them in and the stray dogs out. I have not lost a goat yet due to predators of any sort. So my question now is What all kinds of animals can you keep inside a electric fence? Could you raise a calf or a pony, pigs or donkeys? My daughters have been wanting a pony to ride and I have been wanting to raise a calf or two. Electric fence would be cheap and fast to install until I could afford to build something permanent.
