We have raised Emus for along time. I have never seen them stay in a few strand electric fence for any lenght of time.
We usually recommend a 5 foot high fence for them if they are kept in a smaller area. We have kept them in large pastures that have a lower standard woven wire fence.
Alot depends on how tame they are and how they have been raised.
We have kept them with a large variety of animals-- horses, mini horses, camels, llamas, alpacas, cattle, etc. without any conflict. The only hassle is feeding the Emus seperate from the others. We usually put there feeder on the outside of a gate where the Emus can reach thru to eat but the other animals can not.
When keeping them with other birds- they need to be raised around them so that they are accustom to them. We have purchased adult Emus that were never around other types of birds- chickens, ducks, etc that would stump on them. So they should be introduced to them at a young age.
I would not trust a pond as a natural barrier as they like the water. Our Emu will come and sit at your feet so you can spray them down with the hose for a bath.
