Any tips on fencing. I am getting my two pigs on Friday. We made the pig ark this weekend - really proud of it!! My husband put the fence posts in this weekend - we may need to make the area bigger in a few months but we used all the posts we had. He is going to do the wire netting this afternoon. I thought I mig :-\ht add an electric wire around the inside say 9" high or so. Do you think this will be enough?
