Preferred brand of vitamins/probiotics/electrolytes?

[Fawkes]

I've used a couple of different brands for my ducks, I'm going to buy some more tomorrow while I'm at the feed store so was just wondering what people's recommendations are?

Nutri-drench and Sav-a-Chick are the two most referred to. I haven't personally used either, but thinking of getting Nutri-drench. Also Vitamin B Complex for Niacin issues.

I have never used anything with my Ducks. Only a couple of weak Ducklings.
