If you don't find takers, refrigerate the feed in airtight containers or resealer bags that take most of the air out. It should stay tasty fresh if you can seal out most of the air and keep it cool. For things I put in the freezer I use zip plastic bags that I use a small straw to suck the air out of the almost closed bag and after the air sucks out close the seal while pulling out the straw quickly -- something I learned on a cooking channel about freezer-storing garden stewed tomatoes! We only have 3 chickens at the moment and even 5-lb of organic layer feed/seed is a lot for us to keep on hand which is the smallest size we can get at the feed store. Storing half in the fridge keeps the seeds from hatching worms or weavils -- I add 3 to 5 whole dry bay leaves to dry things like my flour, oat groats, whole dry oatmeal flakes, pancake mixes, dry rice, chicken feed, etc to discourage insects hatching and keep the items in the fridge to stay tasting fresh. I keep my old fridge in the garage rather than giving it away whenever I buy a new fridge so I have plenty of extra cold storage. I need more fridge space than freezer space so keeping the old fridge is handy. Wish my kitchen was big to accommodate the monstrous 28-30 cu ft fridge models but I don't so keeping the extra fridge in the garage is my 2nd best option.
