It is also useful as a natural health support for chickens (ours get a tablespoon in their water once or twice a week during cooler weather) - they love it, and it is supposed to help keep them healthy and improve their digestion.
While it's not all that expensive, if you use a lot of it, it can definitely be more cost-effective (and fun!) to make your own apple cider vinegar at home. Plus, you'll be amazed at how easy it is - and it's a great way to put those peelings and other apple scraps to good use! (Now that I know apple trimmings tend to give our chickens the runs, I'll be using them in this recipe instead after making our annual batch of apple cider this fall...) See below for a super simple and easy recipe that anyone can make at home - no special equipment required.
