Emus can safely ingest plants, fruit, vegetables, meat, grains, feed pellets, and most meals that humans will eat.
The most common type of feed to give to an emu is ratite feed. The average amount of feed eaten by an emu per day is around 1.5 pounds.
Emus love searching for food and will happily eat most weeds and herbs growing in the ground or on trees. They also enjoy things like crushed corn, peanuts, and wheat.
If the emu is very young, it could be encouraged to eat more if you drop a few sprinkles of the feed around them as they tend to peck at the floor and have poor vision as chicks.
It is important to still offer vegetables and grain to help supplement their diet, and doing so by hand can help the taming process along as they grow to depend on you for food.
