While the info from both parties is really sporadic on this deal, let me pose a hypothetical solution to this and let's see how big a man Jonathan is.
Jennifer, if I'm not mistaken, you paid $2500 shipped on this group of animals, correct?
If that is the case, then would you accept $2659 in return for the animals. That would leave you at the exact same place, save some mite treatment and such, as you were at the beginning of the deal.
Jonathan, that would not have her making any cash at all, and it would also have you taking responsibility for shipping inferior quality animals.
If the above statements are true, that would be the easiest solution to the issue.
