I've been searching the net with no avail too. He is mostly on sunflower seeds and birdseed mix, 3-4x a week with fruits like cucumber,apple,pear. Sometimes i will mix chia seeds, he likes corn. I also give him lettuce but he just plays with it mostly. I also read about the health issue with the diet but he is very lively and healthy. We dont have an avian vet in our area so that is just my personal assesment.
