Abandoned Nest :-(

Pearl and Smudge abandoned their two chicks.  :-(  One was tossed from the nest during the day (we sleep days due to Robert's work schedule), and it was too late when I found it.  Its crop was empty.  The other chick was still in the nest, alive, but also had an empty crop.  I tried to handfeed it, but since its eyes are open, it could see that I'm not one of its parents, and it flat refused to eat.  So I moved it to my societies.  So far they're taking care of it, but we'll just have to take it an hour at a time.  I'd say its chances are 50/50 at this point, assuming there is no damage from going too long without food. There's no obvious reason why they would've abandoned the nest, but who knows what goes on in their little "bird brains". So frustrating! :-( Edited 6/17/12 to add that it didn't make it. :-(
