I've been adding both a shot of AC Vinegar plus a shake of poultry vitamin powder in the waterer each time I fill it. Anything wrong with that, or does the vinegar negate the effect of the vitamins?
that's how I was doing it when i started, but a lot of experts told me not to. So now every Monday I alternate adding vitamins one week, ACV one week, electrolites the next.
I use the ACV daily and no vitamins/minerals. If you feed a high quality feed, that should cover it, plus a bit of free ranging if you can, is also beneficial.
