How do you store livestock feed?

A question that I'm sure has many answers, I am curious to know how different livestock keepers manage to store their animals feed.

I keep chickens and I store their feed inside of their enclosed run for convenience. Two galvanized garbage cans can store at least a month's worth of feed and many months more of supplements/accoutrements. Their feed come from a local grain mill and I can fit several standard feed bags in each can.
