I've used the 55 gal. metal drums (that had not had hazardous chemicals in them) with the lids for storing cotton seed and they worked really well (also work great for storing range cubes, milo for the doves & quail, etc.). Another thing I've tried is to build a rectangular box frame out of 2 x 4's or maybe 4x4's. Then get some cheap tin or very thin sheet metal and completely box it in on all sides and the bottom, and make a top the same way. If properly done this will keep your feed, cubes, cotton seed, etc. high and dry and the mice and rats can't get into it. You might get some ants or weevils but that's not too bad. Anyway, this sort of large metal box can be made pretty cheaply and will pay dividends for a long time.
I've also seen people cut holes out and then weld open & shut lids on very large old butane tanks. I'm thinking of having this done on a tank I have that probably has at least a 500 gallon capacity. But to do this takes EXTREME caution, and a welder & cutting torch man (or woman, to be PC) who knows all the safety rules for cutting & welding on such a tank. One thing is for certain, such a tank will last more than our lifetime.
