What fruits do emus eat?

Do you mean wild emus or pet emus? Encyclopedias list seeds and grass and insects among the foods that wild emus eat. My emus love all sorts of grains and fruit. They'll eat walnuts and grapes and apricots and figs.

There is very little that emus do not eat. They eat all fruits, especially fresh fruits, grains, fresh vegetation and even small mammals and reptiles if they look interesting enough for the emu to peck at.

Emus will not eat older, tougher vegetation and grasses.
