Penguin's blood is actually similar to antifreeze. The very first antifreeze for cars was called penguin juice and contained 40% genuine penguin blood.
Unfortunately, this lead to the extinction of the famous Welsh penguins.

Its in part due to the counter-current heat exchange system. This means that warm blood pumped through the arteries into the legs warms up the cold blood being pumped back into the body, this significantly reduces heat loss, even tough the flippers are very cold they are never allowed to go below freezing and with this system their core body temperature is brely affected. As well, the muscles that control the legs and feet are located in well insulated areas to avoid freezing and the flippers and feet are controlled by tendons. However if it is extremely cold they can simply bring their legs up into the feathers to keep them warm. Of course there are the penguin species which don't have to worry about frost like the ones that live in Africa or Australia.

All penguins have well insulated feet. Those that spend a lot of time on the ice, like the Emperors and Adelies, have particularly well insulated feet. Their bodies are superbly insulated and there is a very good blood supply to the feet.

birds have a double circulation system in their legs which mean that the blood in the short blood vessel loop leading backward and forward from the feet is continually being warmed by the circulation of blood within the body.

Read the book!
The blood goes back to the centre of the body very rapidly to reheat it, so the whole chilly cycle can start again.
