BudgieJumper - we talk about kibble in other threads but it is normally healthier for living creatures to get their nutrients naturally vs from chemical goo shaped into squares
So if you are feeding your parakeet a healthy mix of foods - http://www.lisashea.com/petinfo/recipes/healthyfood.html
then that is the best way for them to live. Also, it is far more tasty. Think of yourself. You eat a variety of foods right now. Would you be happy if all you ate every day was colored goo?
