For sure, containers. I never wanted to store feed in the bags. I think I'll stick to the kitty litter containers since I can haul them to the coop, and they're free. If I saved $3 on each bag of feed when it's on sale, and it costs $27 for a Costco tub, I wouldn't break even until I had bought 9 bags of feed on sale. Since it looks like I can't store the feed, even unopened, unless I have a container, it would take me years to break even on even a few containers.
It's not making sense to me anymore.
