I have barrels that my daughter got for me in NC that fit a 50 lb bag of chicken feed in them perfectly.  I believe they came from a medical factory or something to do with prescription drugs, I think.

I use the plastic coffee cans with the handles for use in my barrels to scoop out chicken feed.  I have chickens in four different yards so it is nice to scoop out half a coffee can full of corn and walk along throwing the corn to the chickens.

I often turn them upside down and hang them on the fence posts if I am busy with other jobs in the yard.
