Vitamins for birds come in many brands and forms, like blocks, powders, and liquids. If your bird is on a seed based diet, supplementing is recommended to ensure they are getting balanced nutrition.
Mineral blocks are convenient because you can attach them anywhere in the cage and the birds can chew on them at any time so you don’t need to worry about adding vitamins daily. They are also inexpensive, and long-lasting. The drawbacks are that some birds aren’t interested in them, or like to perch on them and dirty them with droppings. There are a few alternatives, like mineral blocks that are incorporated into toys, or that are shaped as perches.
Powdered vitamins are popular, especially brands such as Prime and Super Preen. This form of vitamin can be sprinkled over seeds, but sometimes may settled to the bottom. It is more effective when sprinkled over fruits and vegetables because it can stick, or, added directly to cooked foods like scrambled eggs. Some powdered vitamins are also water soluble and can be added to the drinking water instead. These vitamins, when stored properly are also long lasting, but can be more expensive.
Liquid drops are one of the easiest ways to ensure your bird is consuming its daily vitamins because they are added directly to the water. Because of this, it is very important to change the water daily to prevent the vitamins from spoiling. Some brands you can add the liquid to the seeds or over fruits and vegetables as well. Liquid forms are usually moderately priced.
If your bird has specific dietary needs, please consult an avian vet before using supplements. Birds on pelleted diets do not need additional vitamins or minerals.
