On my list but thus far I don't feed mine exclusively outside anything but what I buy. I do give them a variety of greens from garden, including variety of fresh herbs. Frozen berries from time to time also, carrots, cantelope, watermelon, but I don't grow other food specifically for them. I buy mix of 5 grain scratch, black oil sunflower seeds, organic brand of laying pellets/oyster shells/cracked corn..I use DE also in and around all areas of pen/ground n coop, including nests.
