I have been searching through the archives and have noticed that quite a few people recommend putting ACV in their chickens water. Although there is no doubt in my mind that changing the PH of the water will reduce algae build up some of the other claims are more....dubious. I do not wish to start a debate about whether or not ACV works or does not. There are hundreds of articles on the web and even on this site with anecdotal evidence that it has benefits. However, try as I might, I have been unable to find any scientific studies that back this up. Literally the only reputable site I could find that discussed ACV was this: http://www.webmd.com/diet/apple-cider-vinegar and that was just for humans. My gut says that this many people probably aren't wrong but being a man of science whenever I see words like "miracle cure" or "wonder product" pop up as often as I do when researching ACV a big red flag goes up in my brain. And even though I respect everyone here and have learned so much from the forum I just don't trust anecdotal evidence when the data size is only a couple dozen birds or less. Does anyone know of a study or some place I can see cold, hard numbers?
