I understand the concern about bio security, but you did offer to buy them back, period. You did not offer to buy them back minus the price of the hatching eggs. What she did was wrong, and you probably are getting ripped off, but you are the one who made that offer. As a business person, if you want to keep your good reputation, I would say you need to stand behind that, even if those birds go directly to the chopping block or to someone else, or are in quarantine for however long one quarantines. And then call it a lesson learned.
