I just accomplished my first pig castrations on my 6-week-old potbelly piglets. I was doing it by myself and had built a holder to secure the pigs. The first one was pretty harrowing, and lots of things went awry, but at last the job was done. The second one went much more smoothly since we had worked out most of the bugs on the first one. So now that I'm "experienced," I'm sure the next batch will go even better. Whew! And thankfully, no sign of hernias so far. Do they show up immediately if they're going to, or does it take a while?
