Almost 3 months ago, my chicken Ginger suddenly couldn't walk and would just lay down, her feet curled up and she couldn't seem to straighten them and she wouldn't eat or drink, just sit there bobbing her head, and she lost a lot of weight. It took almost 2 months of hand feeding/watering her and nursing her back to health. She was finally able to eat and drink on her own, she gained weight and she finally was able to stand and walk again. She was almost completely back to her usual self but still seemed to have problems with her sight. Then suddenly a couple of days ago she is back to the same way she was before. Does anyone know what could be wrong? I would appreciate any insight.
