Thanks guys, she hasn't been near a boar, so I don't think it is piglets! I will see what we can do to insulate her ark better in case she is cold, it is definitely not a lack of straw! Berkshire Boy, you are right, she does need company, but as she had been kept alone for the past several years, I thought she might not take kindly to a companion she didn't know, and had planned to keep one of her first litter of piglets (desperately trying to find her a husband!) - do you think it would be better to find her some company ASAP, and if so, what age of pig would be best, and how do I introduce them?
