Whatever the problem is, Mareks, a stroke, wry neck, or whatever, her symptoms are neurological. That can sometimes be a result of dehydration or a vitamin/or mineral deficiency. Getting fluids treated with electrolytes and vitamins, or water and 3 ml daily of poultry NutriDrench would be good. Mareks can present with many different symptoms. Any problem that can cause brain inflammation may cause similar symptoms.
