I have a little splash silkie, about 20 weeks old. I hatched her from eggs purchased from another bird owner. From the age of about 4 weeks, she started (for lack of a better word) twisting her neck around to where her head was actually upside down. THEN she quit doing it for awhile, and now she's doing it again. I've looked up all the diseases, Mareks, Newcastle etc., but they don't seem to fit what she does. She eats and drinks, and her weight is similar to the other silkies of the same age. Today she's the worst I've seen her be, but I'm not sure what to do with or for her. Could this be some contagious disease? Or just a neurological malfunction? I don't want her to suffer, but I don't want to put her down if anyone has had any similar experiences? All my other chicks and chickens seem fine; no similar symptoms or actions. And since they've always been together, I would think IF it was a contagious disease, they would certainly have begun to show similar symptoms. Please, if anyone out there knows of any similar situations, PLEASE TELL ME!!!
