I discovered this by accident. If you have two black rubber bowls. Fill one of them, let it freeze solid, turn it upside down, fill the other bowl with water.
Next day, the upside down bowl will have absorbed enough heat that the ice block falls out of the bowl, even in very cold weather, today the high was about 15 degrees. We have been well below freezing for the last several weeks, and this has worked like a charm for me, saves stomping on it. With two bowls, one can be watering the chickens, the other, thawing.
