Do my ducklings have a niacin deffiency?

[SummerTheAnimalGirl]

Hi everyone! about five days ago i brought home four Pekin ducklings. they were only one or two days old. I am currently raising them on chick starter, as my brand said it would be fine for ducklings and chicks. Anyways, i know that they need added Niacin in their diet, but because we live in such a rural place, i have not been able to make the trip into town to grab some Nutrional yeast. i will for sure go today though. my question is, will they be ok even though they have not had a lot of niacin for the past five days? thanks in advance!

They will be fine.
Do you have any product like Rooster Booster on hand? Use that for now. Do you have any human grade multi vitamin B tablets? You can open the caplet and sprinkle it on the feed or throw a tablet in their water. I buy the human grade B3. Easy to find.
