While on Mum they do like to wander.. ours come home and get on the heap of grain and have a feed, they chase each other around down the paddock, they sleep in a heap outside the nursery pen, they have their creep feeder and their waterer outside the mums pen, but they do run....every where. 20 sows per nursery pen, some 160+ small pinkor coloured piglets. theya re so comical to jsut sit and watch. They are also very cheeky, I you sit ont he ground they come right up to you carefully though but cautiously, and come right around. the some times come to the hay shed and dart around the bales.....chasing each other around and around.
