In 2011 Pip hatched 44 days after she was spotted (albeit in egg form) in Bobby and Violet's nest (nine days after she was expected to hatch). She fledged 48 days after hatching.
In 2012 the first baby hatched 38 days after the first egg was laid. The two birds were laid four days apart yet hatched a day apart. They fledged on the same day (May 28th), 49 days after the first hatching.
In 2013 the first egg was laid on March the 7th. The first hatching took place 36 days afterward. The first baby fledged 49 days after the first egg hatched. The appearance of the second and third eggs in the nest were reported by others on March 19th but it's not clear when they were actually laid (the Hawk cam was not yet on at the time so the laying was not seen by the public).
