moat of my pairs hatch together and those that do not, hatch any were from 1 to 3 days apart. I would not be worried about it, some just take a little more time then others and incubation can last a lot longer then just shy of 2 months.
She hatched!!!!!! *phew* This is my first clutch so of course I was paranoid But she is sooo cute and looks nothing like her clutch mate which is kinda neat! Of course the only TWO hours we were not home all day and that is when she decides to emerg so i didnt get any hatching pics but that's ok, I'm just gald my very first clutch of eggs were viable and actually hatched out!!! Yeah!!!
