Sorry you’re having to give up the pigs. I pointed out the unregistered aspect to ensure that no potential buyers were confused. If you read the blurb above the advertising section you will see that it is for birth notified pigs only and thus potential buyers could reasonably have expected your pigs to be pedigree from your original advertisement.
You’d be surprised how many people buy unregistered pigs and then get bitterly disappointed when they can’t register the offspring.
Good luck for the future.
