So glad things may work out for your little ones!  
 
 
I am at my wit's ends with shipped eggs lately.  I have eggs that have been shipped and some of them are making it to lock down and then not hatching.  I have tried sitting them upright for hatching, didn't help.  2 eggs out of 10 hatched.    Others just don't hatch out period. 
 
Eggs are arriving packaged well, I am setting them in proper position to let air cells regulate for 1-2 days, weather has been some what cooperative, humidity at 65%-70%, depending if chicks are hatching from my eggs, I know there are no guarantees on shipped eggs, but sometimes it is just gets you down.... 
 
Sorry, just needed to vent a small tiny bit!
