My feed store has literally run out of ALL feed for birds (chickens, quail, turkey... all of them) in the past, but I live in a third world nation... I expect more from a feed store in the USA! I learned though. I have half of a 40kg bag of feed in a plastic tote in my chest freezer.

I got the idea of freezing my 50lb bag (can't get FR in smaller bags) ... I break it down into 2gal freezer ziplocks into another freezer bag, pull out & defrost overnight with the bag open in the house to eliminate condensation. I ferment the feed and so far haven't had any issues.
Wow, that's alot of feed. Freezing's you best way to keep it "fresh". Have you read the thread on fermenting feed? Alot less waste 

Fermenting feed isn't "alcohol", it smells more like sour dough and like pickling.
