When I got my second pair of Kune Kune piglets from Little Blue, they had been successfully bottled reared by her. One, she called Lucky was so tiny .....I kept them in a large dog kennel for weeks, and each morning would dread looking in as I really feared the little one would have been sat on by the other larger one, but no, she survived. She was very small and just never seemed to grow, and it was ages before I moved them to the pig ark as I thought the larger sows would definitely squash her!!
Lucky did grow eventually, but never to be as big as the others, and not something I would have bred from. Do hope you find someone to take your little pig!!
