I have chicks and have small black mold spots in my ACV waterer. I put 1 teaspoon of ACV per gallon of water, and in the base and jug part of the waterer there is mold. I am afraid to give the chicks water in it, but i can't deny them water either. After wiping out the waterer with a paper towel, the mold amounted up to a lot. I then washed out both parts with soapy warm water. Please help!!
