Bought 2 baby ducklings yesterday from a feed store and apparently they dont sell feed for ducks, I got unmedicated chick starter which I heard was okay for them. Today I picked up feed that said was %18 niacin but they were pellets. I was told to not feed them pellets until they were 2 or 3 weeks old and I was wondering if they would be okay going 2-3 weeks without niacin or if it would be ok to grind it up a bit and feed it to them that way. Idk if they can overdose on niacin or not.
