Apple Cider Vinegar in Galvanized Waterers
The Internet Myth
"Add 1 tablespoon of raw ACV to your flock's metal water trough daily to balance gut flora, boost immunity, and prevent parasites."
The Biological Reality
Acetic acid actively reacts with the galvanized zinc coating, leaching toxic zinc acetate into the drinking water. Chronic zinc toxicity causes severe lethargy, crop stasis, and kidney failure. If using ACV, use only food-grade plastic or ceramic.
