My duck that had niacin problems as a duckling but was then given niacin and still receives it nightly has lost the ability to walk. He was fine this morning but when I checked on him today he couldn’t walk and both his feet were curled and looked shriveled? I have no idea what would be the cause of this and what to do. He doesn’t look like he’s been attacked because there’s no blood.
Please post pic of his legs and feet and what niacin your giving along with age an breed.
