I have three one month old Eastern Wild Turkeys (mix), Yesterday one got real weak and acted like it couldn't stand at all, no visible leg or wing breaks, just acts very weak, and today I went in to check on them and one was lying on its back,flopping all around, it couldn't get up, when we got it up it couldn't stand, had no balance, just fell over and flapped all around, kicking its legs all around, and its head and neck were just twisting all around and going from side to side. What does this sound like, what do you think is the problem. I put all the turkeys and chicks on antibiotics today as well just in case they had something infectious. Please help me. Just desperately need any kind of help. Thanks in advance.
