Hey guys, I have just noticed my duckling (2 weeks old) cant walk properly! She tries to but ends up just falling over! One of her feet isnt spread out like it should be either and its all closed up! Does this sound like a niacin issue or maybe something more serious? No vets near me look at ducks so Im pretty worried about her, shes the only yellow duckling I have ever had and I really dont want anything to happen to her! Any advice would be great! I have seperated her from the others (which are doing perfectly ok) and supplimented her food with some niacin. Anything else I can do for her?
