Gosh the only thing on that list i can get is the oats, I was able to buy wheat back in the summer last year, no mills around here and a feed store that won't order things for me. Very frustrating.I am feeding a mix of oats, wheat, triticale, and lentils that I get from a local farmer. My business partner and I have found a different source for added protein, grit, necessary vitamins and minerals and fats needed. I think it ends up about $10.50 for a 50 lb bag.
The birds like the whole grains better than processed feed. It took mine a couple days to realize it was edible, but now they scarf it down.
