Hi Anne,
That backs into my primary concern. I have plans to stop raising pigs. I am 76, and my plans are to have the pigs gone by the time I am 80. I had a concerning incident with the boar a couple of months ago. I got in his pen to make repairs, and he felt the need to come up and use me as a scratching post. He had no intention of harming me; but things could have gone very wrong. Normally I toss a cup of grain into the opposite side I will be working on. This time the need to rub up against me was stronger than the need for food. Anyway, I was struggling to keep my balance.
