Hi Guys !! I have a serious issue to discuss here with : My Partridge Brahma Cock of 3 months of age, fully covered with feathers even shinny feathers has issue of LEG SHIVERING, it is healthy and perfectly fine by looks, eats good and no visible sign of sickness. This issue became noticeable 20 days ago, As I said Cock is looking fine so we didnt consider it much, but now It needs some attention. this birds is oversized compartively of its age. Cock have a plenty of space to run around, and eats good. at very beginning Bird is gone through a complete antibiotic course, also with routine Vitamins. But issue is still exist , No visible injury even muscle relaxation course also done. I would like to know what would be the issue with it, and how to cure it.
