The varied climates is definitely a factor when storing food. With such a small flock, it takes us a couple of months to deplete a bag of chicken feed so I can see where freezing it here is a value. For you fine folks who live in the deep freeze, you absolutely have to prepare for blizzards and extended lock ins, not to mention power outages when ice freezes the electrical lines. I remember those days. I would certainly take advantage of the natural freezer for winter and store feed outside in air tight containers or aluminum cans, something that doesn't sweat inside from moisture.Makes sense. We don't have a car that can handle snow and so we've made our last feed store run for the winter. It's the same as stocking up on people food (mmm beans) when snow is in the forecast.
