The fourth and final egg laid by Peregrine Falcons in their nest on the spire of Norwich Cathedral has now hatched.
Staff from the Hawk and Owl Trust say the chick broke its shell at around 11am.
The first egg hatched on Saturday (26 April) just after 7:30pm, the second and third eggs hatched yesterday (Sunday 27 April) at 2:30pm and 5:30pm.
The chicks will now spend the next five weeks growing before they are ready to fledge.
