Ok the link I already posted on here said it. Maybe it isn’t accurate maybe it is.

In this post by
@Miss Lydia,
“Animal products contain niacin, so mealworms, earthworms, slugs, fish (some people give their littles the tiny feeder fish you can get at pet stores), those things boost niacin. It's also called Vitamin B3. It is necessary for proper development of the nervous system. Most often, seems to me, it is noticed when it affects the legs,
but we have read of duckling seizures stopping with niacin. Some have also found ducklings Vitamin E deficient.”
Sorry I had to bring you into this
@Miss Lydia.
And what does it matter? By treating it like niacin deficiency you also treat the thiamine deficiency by using the B complex so what is there to argue about? If I’m wrong show your proof.
