When the duck turned and came closer, I noticed it had signs of angel wing. This is a syndrome affecting water birds that eat too much bread. This causes a nutritional deficiency in vitamins and minerals combined with a high level of carbohydrates and sugars. It affects their ability to fly. If you enjoy feeding ducks, better to bring along some cracked corn or frozen peas.
