If you're seriously considering making and mixing your own, there are places where you can get grain mills, both electric and manual. You'd have to do some research on what was most available for base grain in your area and what your nutritional requirements are. There are probably a fair number of "recipes" out there or through this forum that will help you with the percentages and supplementary vitamins and minerals. I'm afraid the cost of feed is hitting all of hard and I sure don't expect it to get better in the near future. Good luck!
