Thanks for both suggestions. We initially looked at using relatively small plastic or metal bins set outside the barn with a grinder and an auger on the bottom to feed the grain indoors as we needed it, but the costs greatly outweighed the benefits for us. We cash rent our tillable ground out, and have no on-farm bulk grain storage facilities at all. Even if we grow as planned, we would likely go through less than 15,000 lbs of grain a year for the whole herd. Since we buy grain from the local elevator and have them haul it to us anyway, it is only a small additional charge to have them crack the corn before delivery and also to have them make up a basic "oat-based" feed mix. We add the corn, plus any oil, molasses, medications, ionophores, extra beet pulp, etc. to that base mix as needed for each animal or group. The monetary benefits we see by building some storage of any type are primarily saving the cost of bagging the feed, and reducing the delivery charges by reducing the actual number of deliveries. We estimate the most we could save by switching to this system would be about $400 per year for the next few years anyway. We can build three wood bins that would share common walls for under $500 worth of material, and there would be no maintenance or energy costs. We have room in the feed area to build these L- shaped bins about 8 feet tall at the back and about 3 1/2 feet tall at the front, with a total depth from front to back of about six feet. We would vary the widths to make 3 bins of differing capacities, but in total we would be able to store about 4,000 lbs of bulk feed. We don't want to build this and and up redoing it, but so far we have only seen one example of a wooden bin design that appears to be well thought out at all.
