We put our feed just outside the coop in black rubber garbage cans that have "critter-proof" lids meaning they have metal latches that I defy any raccoon to get open. That being said...we recently found out that rats can and will chew through that rather thick rubber to get at the scratch inside - they don't seem to care much about the feed, but they really want the grains. My feed store carries galvanized steel garbage cans with locking lids that I've been eyeing up every time I'm there, but the price tag attached to them is outrageous. I do believe in the end I will probably go for the steel ones since I need to replace two of the lids and they don't sell just the lids (go figure that one out!) and to be sure if I was to do it over, I would have grabbed them before the hike in oil costs which seems to have sent the price of everything through the roof.
