In response to questions from Westridge Elementary 3/4 and "Twosue" who both asked about how the mother will take care of the eggs once they begin to hatch---She will continue to sit on both the hatching and unhatched eggs. Hatching can take as long as 48 hours and the chicks are not able to thermoregulate (keep themselves warm) for more than a week after hatching. She will continue to keep both the nestlings and the eggs warm for some time to come. When she is not feeding, the scene appearing on Raptor Cam will appear much as it does now for the next couple of weeks.
When the nestling emmerges it will quite wet and will appear mostly pink and unfeathered. However it actually has a significant amount of down that will dry out and fluff up within a few hours.
The pictures below are of peregrine eggs hatching at the Audubon facility to give you an idea of what things look like.
