0: Emperor Penguin eggs take 65 to 72 days to hatch.
In this specific case, the parents chose not to incubate it,
so the egg was incubated by our zoo specialist team for that entire time.
Normally,
the chick would start to break through the shell on its own for our chick.
It broke through the initial membrane,
but was never able to get through the shell.
After several days of no progress from this chick,
we realized we actually had a beak malformation that was going to prevent it
from hatching on its own. We decided we needed to go in and start helping.
That entire process takes almost three days. At the end of that three day,
we were able to successfully hatch the chick,
and we had one of our first emperor penguin babies in over a decade.
