I use large chest freezers. The seal really well and are rodent proof. This is were I keep my horse feed( sweet feed with alfalfa pellets) , chicken feed ( layer pellets, cracked corn, oats and sunflower seed) and my dairy goat feed. I also keep treats in a small space in them, ( horse treats, whole ear corn and some veggies now and then.) Each large freezer holds between three and four hundred pound of feed, depending on weather or not I built dividers in them or not to keep different feeds all in one freezer.
