I feed them some sunflower seeds, corn, and grains, along with a generic commercial feed if they need it, but mostly they forage. I have large compost and wood chip piles for them to scratch in for bugs, and they chase down lizards as well. I have a garden and they get all the leftover vegetables, and I also have banana, mango, fig, coconut, and various other fruit trees that they get a lot of. A very wide range diet, but they're very healthy.
