Pumpkin and Spice are said to be settling in to the zoo well, being looked after by their parents Maneno and Jozini.
They are now part of a colony of African black footed penguins at the Zoo.
Team leader of the bird team at Banham Zoo, Sophie Imhof said:
“We couldn’t be happier to welcome Pumpkin and Spice, especially at such a magical time of year.
With African black-footed penguins under so much pressure in the wild, every new chick really does matter and these two are a lovely reminder of why conservation work like this is so important.”
