With the deal happening so long ago at this point, there isn't much to be done about the sexing mistake probably. Most breeders will make it right if caught soon after. Other than that being a female instead of a male, price wise works to your favor. I know it puts a kink in your plans, but an extra female is never a problem.

Don't worry about the lock either, most animals know their reproductive capabilities far better than we do and she'll be fine. Mind if I ask why there were two "males" in with the female? Were you hoping to spark one of them to breed through fighting/competition?
