I have to agree with Dan and Lyn, you cannot just let your bird eat what it wants and to do so is irresponsible, in the wild yes they eat what they find but they don't find cookies and other junk foods, they find lots of fresh things to eat and just like children we have to guide them to healthier choices, you wouldn't allow your human child to only eat junk food if that is the only thing they would eat if given the choice, its up to us as caregivers to provide the healthy choices for their nutritional needs.
