What was the single codom you wanted them paired to? Unless it was a pretty high dollar codom it sounds like you were getting the short end of the stick right from the beginning to me (even if everything went as planned). I would just take it as a lesson learned and buy your own male for this year. Normal females that produce ten eggs are hard to come by. I'd keep both and make your own next year and don't deal with the person that you did the loan with again.
