PLEASE HELP, Took a duck from a family members house due to the duck not being able to walk after researching found that was probably a niacin deficiency, started duck on vitamins and niacin that day, added the supplements to feed and water, niacin drops are given orally through dropper. His strength in legs is better but he refuses to stand. I do exercises with him everyday, we swim, scoot in the grass and I manually stretch his legs. Still he refuses to stand or walk, I have taped his legs to try to get them to straighten out nothing seems to be working. Please see pictures, I’m at a loss and I want him to have a good life but I’m now debating if this is a good quality of life.
