There are a few health benefits that come from grapes and raisins. These fruits are a great source of vitamins and minerals such as iron, potassium, and fiber.
Raisins are also composed of 96% carbohydrates, 3% proteins, and 1% fats. It’s believed that one cup of raisins alone contains 97.7 grams of sugar.
While chickens can certainly eat grapes and grape seeds right off the vine if you are lucky enough to have them in your backyard, store-bought grapes should be prepped before feeding.
