Cold maybe , do the freeze no. Penguins and many other water birds have what is known as a counter-current heat exchange system. The warm blood flowing into the leg warms up the cold blood going back to the body. This minimizes the amount of heat loss. As well they are able to control the blood flow in order to insure that the feet don't actually freeze.By doing this they minimize the amount of heat lost to the environment. If it's very cold they will bring their feet into the feathers and help keep them warm. The muscles on a bird's leg are located closer to the body in feathered areas where they are not as prone to frost damage, the feet are controlled by tendons.

There's a book in Asda called 'Why don't penguins feet freeze?' and it has the answers to other Q's like this. It's only £3 aswell, I think.

there is a large supply of blood circulation to their feet (and also wings).

Same reason why they don't ever get insulted, they have thick skin.
