Btw, how do you make flour from scratch? (Impressive!). I made bread for awhile, but never flour...
My mother used to do this when I was young and we were dirt poor (my father supported a family of four on a Ph.D. stipend). She would buy chicken feed and grind it into flour with an attachment on her mixer.
You can buy whole grains that are for human consumption once you're not quite so poor too! It's fun, provided you have a mill or attachment (there are manual and electric ones) and it's even quite sensible as, unlike flour, the grains keep practically forever so you can buy in bulk; we get 8kg buckets.
