Oh, just caught where the 30 days came from, because I said that it was the only egg in the incubator for the last month. I only said that because this was by far our LAST clutch of the season, i.e. a whole month later than the second to the last clutch. It has been KILLING us waiting for this one egg. So ya, it had been incubating for a while before the other eggs in the incubator hatched, putting yesterday at day 52. Sorry for the confusion.
