Chester Zoo baby boom sees animals up by more than a third

  • 22 January 2013

Chester Zoo is in the middle of a baby boom.

Over the last few months, animals such as black rhinos, giant anteaters and Asian elephants - which are endangered in the wild - have been giving birth to babies at the zoo.

Many of these species are extremely difficult to breed in captivity, so it's a real achievement.

The boom means the number of animals there is up by more than a third in the last year.

Nel's been finding out the secret of the zoo's success.
