Hello and welcome! You’re duckling is beautiful. What are you giving her to increase her niacin intake we recommend liquid B complex one ML per day. You can pour it over a treat like mealworms make sure she gets it all. Keep giving it and also add 1 tablespoon of nutritional yeast per cup of her feed, do both things for best results.
Some niacin will not work if they are time released or flush free they will not work for a duck because it goes through her digestive system way too fast. Here’s a picture of the liquid b

complex. It says injectable for cattle, but it is given orally to ducks.

Hi there

I'm so pleased you're helping this lovely duck, I hope everything goes well for her.
As @Debbie292d has already said there is a thread especially for ducks so maybe you will find a lot more answers there.
