Rolled oats, barley flakes, millet, chia seeds, flaxseeds, amaranth flakes, sesame seeds, crushed nuts (almonds, walnuts). Try to keep nuts and seeds as a low proportion of the mix.
Chopped raw vegetables
Kale, bok choy, parsley, broccoli, brussels sprouts, carrots, fennel, beetroot, pumpkin, sweet potato, capsicum, snow or sugar snap peas, parsnips, cauliflower, beans, corn, chillies, pomegranate, paw paw, tomato, passionfruit, kiwi fruit, melons.
Finely chop all ingredients or put in food processor until very finely chopped. I find that processing in small batches and with low settings are best to avoid creating a soggy mess. Mix it all together in a mixing bowl.
1 cup dry quinoa (makes about 2 cups when cooked), 2 carrots, 1 broccoli, 1 medium beetroot, 6 chillies, ¼ cup flaked almonds, ½ cup rolled oats. Cook quinoa, chop all other ingredients and mix everything together.
Once made, refrigerate enough for 3 days. Freeze the rest in portions big enough for 1-2 days. Depending on the size of your bird, you may do this in an ice-cube tray, small Tupperware containers or freezer bags. A convenient freezer method is to scoop the mix into the cups of an egg carton, pressing firmly down. The cups can then be fed frozen in foraging toys.

Depends on your bird, but as a rough guide.
