Does anyone else have an opinion on apple cider vinegar for their chooks?
I don't think thier deaths are anything to do with the ACV. Even if it is a slightly high concentration, if they have no other water source they will drink enough. I've put upto 2-3tablespoons per gallon without any problems or apparent reduction in drinking.
I put ACV in their water for atleast 3 days per week, if not more. The ACV may or may not help to control worms, but I know from experience that ACV definetly helps to clear their sinuses. My flock has got respiratory problems from somewhere, and If I don't put ACV in their water , the worst ones affected start coughing and sneezing as their sinuses start to get blocked. ACV sorts any respiratory problems out. With ACV I am not at all concerned about repiratory problems anymore (atleast not viral ones, oregano oil should keep any bacterial ones at bay).
I also put ACV for weeks in a row in their water during periods of high stress e.g new members added to flock, or bad weather etc as I believe It does seem to help reduce stress and any potential illnesses related to the stress.
ACV will only have positive effects on the flock if any. It should not have any negative effects. ACV, Oregano Oil, Garlic and Red cabbage are the most important health foods for chickens in my book.
Most chicken deaths are put down to "Unknown cause".
