Ok...it is time for confessions.... I have doubted the apple cider vinegar theories for chickens...mainly because my mother is a big believer in the benefits of ACV and all thru our childhood we were dosed with ACV (whether we wanted it or not). We couldn't sneeze around our mother without getting a tablespoon of the stuff. Friday evening my 5-week-old roo Faverolles was lethargic and barely moving. I examined him for any clear signs & symptoms of a particular illness, but nothing stood out enough to make a diagnosis. Without an avian vet nearby and armed with the only knowledge I had...I dosed his drinking water with vinegar. He was so weak Friday night, that I honestly doubted he would make it. Saturday morning he was moving around more but wasn't eating. I kept up the ACV. By Sunday evening he was eating! This morning (Monday) he was back to picking fights with the other roo chick & preening his feathers For The Record: I used raw, organic, unfiltered apple cider vinegar - 1 tablespoon per gallon So to everyone out there in BYC land, that has ever suggested ACV....THANK YOU!!!!!
