I have a 9 week old Rouen mix with either a khaki Campbell or welsh harlequin duckling. She has always been a little off. She was hatched from the tiniest egg I had and is still the smallest duckling. She doesn’t run from people or “scary”things like the others do, in fact she doesn’t really run at all that I’ve seen. If the other ducks run off or get separated from her she will stand there for a bit before she starts quacking for them, then she starts kind of walking(maybe speed walking) towards them. It’s like she’s kind of slow mentally. She eats and drinks like normal. Her legs look fine to me, they don’t tremble or anything and she gets plenty of niacin in her diet so I think it might be a neurological issue. She is one of the ducklings I wanna keep, but I don’t want her to be living in pain if it is a physical issue. Has anyone had a duck like this before? Was it able to live a happy life? Thank you for any answers
