Sorry about your chicken. The problem with vitamin E is that it is fat soluble, and it will accumulate in the body if too much is given. 400 mcg per day is usually given for a time, and that is the daily human dosage. So I would not keep giving that much after all this time. It obviously was not caused by a vitamin D deficiency. Have you also been using thiamine or B1 in addition to the E? Wry neck can be a symptom of vitamin E or B 1 deficiency, head injuries, and seen in some diseases that affect the brain, such as Mareks and others. Some seem prone to wry neck by heredity. Have you seen improvement? Selenium is found in cooked egg, sunflower kernels, nuts and seeds, and too much can be harmful.
