When my Emu chick was sick I tried finding anyone who could give me information. I called 3 different universities, several zoos, vet offices and I found no one that could help me. I am in Wisconsin so Emus are fairly unheard of. My advice is get on the horn and start calling any place you can think of. Vets, zoos, breeders, and universities. If you are in the south you will have better luck.
My best wishes to you. Owning Emus is very interesting when things go wrong. They are generally healthy.
