Has anyone had an emu go bad out of the blue. I have 2 emus El and Ed, El is almost 2 and a half years and is a perfect creature, gentle lovable sweet, Ed is almost 1 and a half and this week he has decided to attack my husband several times, hissing biting the whole 9 yards. We have no idea why, usually Ed sits in his lap, he tried taking his glasses off, changing clothes, offering him snacks, Ed just keeps trying to get to him. I have to hold him to let Rog walk by... any suggestions?
