Hello! My poor 4 week old Pekin Duckling is bow legged (both legs) and it is getting worse on one side. One side I can tell is harder to walk on and the toes on one leg are starting to be close together versus farther apart. At first I thought it was a Niacin deficiency, but after getting our duckling niacin for over 1 week without any signs of improvement, I am getting worried. Bad leg is not getting more bow legged, but it is getting harder for my duck to walk on. Still eating and drinking a ton...but I am wondering what I can do to help my poor duckling. ANY advise would be appreciated!
