Hi, I have an eight year old hen that has tumours. She was on antibiotics for a week and came good. She started eating again and more alert. She all of a sudden stopped walking. She is eating well and alert, but just has no strength in her legs and cannot stand or walk. I'm not sure if this has to do with the tumour condition or something else. I need to know if this is treatable and can get her back walking again. Thankyou
