I am ordering in a bunch of whole grain mix for my birds and will leave it in whole grain form to preserve the nutritional quality while in bulk storage. I will ferment and feed a small amount in the morning and evening then fresh grind weekly to provide their free choice ground meal/mash/crumble ration to keep things as fresh and nutritious as possible. Thing is, I need a small grinder/mill/roller. I have read of people using brewers mills to simply roll the offerings but in talking with the various roller mill makers they are cautioning me on the hard grains such as peas and corn being hard on the rollers. I know I can get a CS Bell model 60 or something and mount a motor on it and that is what Harvey U. uses but I would like alternatives if you know of any. I am only needing to do 50 to 100 pound batches at a time a few times a week. I am pretty much done hoping of getting a used one whether it be a small pto driven hammer mill or the likes as they are really slim pickings; I have been looking for some time and the ones at farm auctions in the area are fetching a fortune. Any ideas or alternatives for me to look at here.
