I use Kaytee, but it is blended daily with a pinch of pine nuts, pinch of walnuts or pecans and 1 crushed La Fabers seed ball. I have two greys - they also get a daily dose of fresh veggies (carrot sticks, pea pods), fruit (bit of banana, two or three raisins, apple bits), and meat. (white meat of the chicken - small amounts a couple times a week) They are also extremely fond of whole grains and share oatmeal with me frequently. They are not interested in chile pods at all and cannot abide pumpkin seeds.
