Fruit Juice vs. Water --------------------- Whenever possible, fruit juice (apple juice is a good starter) should be substituted for the drinking water. As an alternative, Tang (or its equivalent) can be added to the drinking water. This may not be a practical suggestion for birds that habitually bathe in their drinking water. These additives or fruit juices provide more nutrients (vitamins, minerals, etc.) than water alone, and they help to mask the taste of other items (vitamins, antibiotics if necessary, etc.) that may be added to the drinking water. Fruit juices that produce stains (for example, grape juice) should not be used. Fruit juices or water to which perishable items have been added must be changed every 12-24 hours to prevent spoilage, and perhaps even more often on especially warm days. Even plain water should be changed with the same frequency for the same reasons.
