ACV should not be used as a preventative, which is often why it is put in the water. people often use it as a preventative for yeast infections. but what happens when they do this is that they just make the yeast immune to the ACV so when the bird does get a yeast infection, ACV will not work to clear it up. so best not to do it. if you bird does get a yeast infection, you can put 3-4 drops in their drinking water to get rid of the yeast. how it works is that its acidic enough to break down the yeast off the crop walls. also, the constant use of it can also cause digestive problems like ulcers (because its not good too feed acidic food regularly like that). best used as a treatment, not a preventative
however, if your bird gets a yeast infection, after you use the ACV, its best to give your bird probiotics a week afterwards. ACV will clean the body of the good bacteria too. Which will leave the body open to infection. Probiotics boost the body's good bacteria to give a stronger defense against infection. This way you prevent your bird from getting reinfected or infected with something worse. so after any antibiotic treatments or ACV its important to give probiotics for a week later. Plain yogurt is a natural probiotic or you can get the powdered stuff to sprinkle on their food.
