Need some desperate help (UPDATED with pics)

First and foremost, you have *got* to get that bird on actual feed immediately. Cracked corn is not even close to being an adequate diet, especially for a young growing bird. She looks extremely malnourished for three months old.

I would make getting her on feed absolutely the top priority. Yes, consider adding some brewer's yeast or niacin once the feed situation is worked out. Getting her on food should take precedence though.

you can't use those viatmins because they have iron and other things in the wrong dosages for ducks... you could very well do more harm than good. brewers yeast or niacin pills are not expensive and easily available...

Your ducks needs adequate feed right away. He looks 6 weeks old but is three months old and is danger of passing away young if not fed right. If you have to buy it online, i would do so, even if it's a small bag while you locate a new feed store.

It needs to have 16% protein. it can be duck feed, chicken feed, or gamebird/turkey feed. any of those would work ok if the protein is okay. In the mean time while you get food, feed your duck some treats that have a lot of protein, like scrambled eggs, dog food, worms, feeder fish, koi floating fish food, even white meat chicken... you can find all sorts of treat ideas by clicking the link in my signature (go to the protein section). Feeding him some veggies and fruits would help too. This however is not a substitution for feed.
