We had two pigs last year, which are now in the freezer. We live in a substantial wood, and the pigs did a good job of clearing a small area, but we would like to make use of them and clear more. Does any one have ideas for portable fencing/pen which can be moved easily every couple of weeks, but is also big enough for them to run around a bit. I don't want electric as we have 4 small children. My husband is good at DIY and could make something, but some ideas would be useful! Many thanks
