A steel drum that has the screw lids, for liquids. I don't know what it had in it but does not leak. I do have a large lid for it with a ring if you could sant to cut out the top. Not sure how well it would seal but would probably keep out rodents from your feed. Would also make a good burn barrel. . Also have two smaller steel drums - 20 gallons, without lids. They may be antiques. $20 each. Also have about 3 plastic barrels that hold about 15 gallons. - $10 each. Three 55-gal plastic drums - $20. Can deliver to the Missoula area. Give Doug a call or text for more info or pics. MT area code 274.3706
