Years ago we bought 2 small feeder piglets. We had a pen built for our chickens that was covered and fenced with heavy wire. We checked all the wire and it was sound with no holes or gaps. We put the piglets in it with a small hutch for shelter. They were fine for several weeks. One day they disappeared. After searching all afternoon, we figured they had gotten out and coyotes had taken them. When we went to feed and milk the dairy goats that night we got a shock - the piglets were inside their pen! The same thing happened the next day. This time I went in and checked the shelter, feeling in the straw bedding. No piglets. Milking time they were inside the pen again. This happened for several weeks until one evening they were laying outside the pen. This time I went over every inch of wire, pushing and pulling, and finally found back in a corner where the wire overlapped by about 12' that one piece would push far enough out to allow the small pigs to escape. Then the stiff wire would snap back into place showing no sign that they had gotten out. They would get back in the same way until all of a sudden they were too big to squeeze in!All this makes me realize that even though I'm trying to make things work on a budget I can't ignore gaps when I have goats.
