Yes, ducks can eat red cabbage, and it can be a nutritious addition to their diet! Red cabbage is packed with vitamins C and K, antioxidants, and fiber, which can help support their immune system and digestion. You can serve it raw or lightly cooked, but it’s best to chop it into small pieces to make it easier for ducks to eat. https://factaboutpets.com/can-ducks-eat-cabbage
