I feed mine several grains. As I don't add salt or sugar to my foods, I will fix enough and give them to the birds as well. Here are some of the grains that I share: steel cut oats (higher nutrient content and more filling), quinoa, amaranth, teff, wheat berries (which I also sprout up nicely), brown rice, chick peas, lentils etc. They never get anything hot as that can burn their crops and they get a minimum of 3 veggies and 2 fruits each day plus their sprouts. Yum!
