My 4 month old buff Orp. started having seizures yesterday. She is otherwise healthy, still eating, drinking, and growing like the others. About a month and a half ago she was having some problems walking, kept tipping over sideways. I got some different food that my local store recommended and that seemed to work. Not sure if the two issues are related or not. We have still been feeding her the special chick food with extra additives... The seizures last only about 10 seconds but she has them pretty frequently (falls down, starts shaking, then kind of scratches at her face a bit, then legs get very rigid). Any ideas what might be wrong and solutions? Thank you.
