Usually I show market goats but this year i decided to show a market sow just for fun. I’ve been working with her in a small pen for about three days and then I began working with her in the goat field that surrounds the pig pen. The problem is that she will not leave the fence. Her sister stays behind and my sow will not leave her. I’m not sure what to do about this as I’ve never trained a pig before. Any suggestions?

Time and practice. I would see if you can feed her in the field. Most pigs will follow a feed tub.
