@Bothersome Bob Barber I'd look around your area for someone missing an emu.For some reason this site popped up when I asked the internet what Emus eat. Then I saw some other posts about Emus, so here I go also...
An Emu just wandered into my yard in southern Texas. What do they eat, please?
Ah... that's why he has set up shop by our bog.My google search for "Emu diet" returned the following information: Emus eat a simple diet of fruits, seeds, growing shoots of plants and insects. They swallow small stones (called gastroliths or gizzard stones) which stay in the gizzard and help grind up food. They require a large amount of water, drinking 9-18 litres daily.

Other websites pretty much echoed the above, and all stressed that they must have copious amounts of fresh water available to them around the clock, stating that they will awaken due to thirst several times nightly.
