I have a 3 week old buff pullet that i noticed is tilting her head back on her neck and swinging it back and forth. She only really does it when she is drinking water. I have watched some videos on wry neck and some of them look similar to what she is doing. In reading about wry neck i found that vitamins supplements could cure it? I am not sure what to do for her or if i should seperate her from the other chicks? Here is a video of her this morning to get a better idea of what she is doing. Please help!
