I noticed mold growing in my water jug that I keep in the house for my daughter to fill the chicks water container with. I keep a 1 gallon container on my counter and I add a tablespoon of Braggs ACV. and keep it ready for her to refill. Has anyone else had mold grow in their waterers when using ACV? I'm kinda concerned now about putting it in my big automatic waterer with the nipples if it will grow mold. What are your thoughts?
