A single emu can be happy with other animals, especially if raised up with them from a chick. My one, Jazzy, pictured above is more a loner when it comes to the other emu. He was raised up by himself for the first month before I got another, and although he is friends with Merlin, he prefers the other animals and us. I tried to get a girl for him, but he doesn't like her... but Merlin has bonded with her. Jazzy still spends most of his time with us and the zebu, goats, mini horses, llama, alpaca, horses, donkey, GP's, and fowl.
