Along with Brahma they are not thought to be derived from Gallus Bankiva, like nearly all other domestic poultry. This is evident from both their character and bone formation. Despite research, scientists have not been able to explain the variations between heavy breeds like the Cochin and other poultry. No Gallus has been discovered from which modern heavy breeds are derived²

Cochins came to England for the first time in the mid 1840’s where they caused quite a sensation. These original birds were buff in colour and one of the largest breeds that had been seen at that time with adult males weighing around 5kg. The thick plumage enhances their already large size and gives the impression of greater weight than actually exists. One of their most distinctive features is the plumage that covers the leg and foot. They come in several colours including black, blue, buff, white, and partridge.

They are mainly kept as ornamental fowl though their large size means they are very capable of being a table bird. It is thought they were originally developed for their feathers which were used to fill pillows. The profuse leg and foot feather makes it desirable to keep the confined in bad weather where runs become muddy. Keeping them penned prevents the birds from being mired and collecting balls of mud on their feet. Cochins are very calm birds and make excellent pets. They are renowned for becoming broody and make very good mothers. They lay up to 150 tinted eggs per year.
