The youngest of the chicks is much
less developed. Unlike some birds, like ducks, where all eggs hatch at once and
the young all develop at the same rate,
peregrines begin incubating with the third egg that is laid and a fourth is laid
2 days later, which means the first three eggs hatch on the same day and the
fourth two days later. The younger catches up rapidly to its older siblings.
Peregrines do not practice siblicide, like eagles and some other raptors.
