The Smithsonian Channel is rebroadcasting this show on Tuesday May 3rd at 11 am. I watched it a few days ago and it is fascinating with great videos with sounds of the eggs in the nest and how the pre hatchlings communicate with each other getting ready to make their way to the surface all at one time. And the process of how they work together as a group to do this. Other than the eggs hatching the whole hour is full of new information about the Ridley's.
