Cochins go broody alot, and they make great mothers!
This is an article from Wiki that I found.
As above, the most distinctive feature of the Cochin is the excessive plumage that covers leg and foot. The skin beneath the feathers is yellow and the egg colour is brown. Eggs are also medium in size. Standard weight is 11 pounds (5 kg) for a cock, 9 pounds (4 kg) for a cockerel, 8.5 pounds (3.9 kg) for a hen, and 7 pounds (3.2 kg) for a pullet. Colour varieties include buff, black, partridge, blue, silver laced, splash, golden laced, and white. Cochins also come in a variety called frizzled, in which the feathers are turned outward. Cochins are well known as good mothers, even as foster mothers for other breeds, and they can lay many eggs, but usually not for extended periods of time. Cochins are also known to be good pet hens for the garden, as they are tame and regarded as one of the most 'friendly' chicken breeds. Cochins are quiet chickens. They scarcely crow or cluck, only when laying eggs.
