I have a small hut at the end of my driveway, and we put a small fridge in it for the summer to keeps eggs handy for our customers, and they dont have to come all the way up to the house. This works great in the summer. However, come winter, when it gets cold, all the eggs freeze and crack inside the little fridge, it keeps things cold, but cant warm things up. Do I really have to put a heater in this little hut? It is a little too big for bulb to do much, with electricity costing what it does, that would eat up all our egg profits! I am pretty handy at building things, does any one have any plans or ideas? How does everyone else keep thier eggs in road side situations from freezing during the winter? Thanks!
