Good question. They did root around a bit, but nothing like what you see in the bush. They were well behaved piggys. Their pen wasn't very high and they didn't jump out. They were well fed though. Bay Of Islands is an amazing place to live. I was down there a couple of weeks ago for Search and Rescue training with the Coastguard. We took the boat out and did some doughnuts out from dove bay. Great fun. We had a pig on a spit over New Years. Came out exelent.
You can lead a dog to water, but you can't make him a horse.
