Hubby and son took the pigs this morning. We had put the trailer in their pen for a few nights and they were sound asleep when he shut the door. He said they were still sound alseep when he opened it at the other end!
Apparently our girls just trotted out straight into the pen - which was good because at that point he realised he had no pig board or bucket! They had to be moved again (which they beautifully complied with) when another smallholder turned up with his 3 GOS and began to literally kick them out of their trailer through the side door just because they wouldn't budge - @*!% idiots

The vet had to step in and told them to put their pigs in a different pen (where ours were) so they could calm down before they got taken through. So ours basically jumped the queue.
It did make me think that actually although the tummy tickles and scratches and hugs seemed perverse at times, they probably went a fair way to help the pigs stay calm and approach new places/people with confidence instead of fear.
I do miss them already though
