Ollie lives in the Etosha National Park. He emerged from the largest egg in the world -- as large as twenty-four chicken's eggs. In this part of Africa, the temperature is often over forty degrees Celcius and Mum had to brood the eggs -- not to keep them warm, but to keep them cool. Dad helped out too. Ostrich eyeballs are bigger than their brains; they can even see behind themselves without turning their heads. Their feathers do not have the little barbs that join them together, like normal flight feathers. That is why they look so light and fluffy.
