Help. 3 week old duckling wobbly

[FowlPrincess]

Any ideas on why a 3 week old duckling would suddenly be wobbly? He is a runner and has been very healthy to this point. They were on chick starter. I just changed to Dumor starter/grower. Any advise would be much appreciated, I dont want to lose him!

Is he eating, drinking & pooing okay?

What are you giving for a Niacin source?

Sounds like a Niacin deficiency. I'd start the duckling on some Nutritional /Brewers yeast 1 tab per cup of feed or 150 megs of plain niacin in 1 gal of water not flush free or time released all ducklings need to be supplemented on Niacin in some form till 10 weeks of age. If fed chick feed.
