Other link its origins to an influx of horses during the Bronze Age. However, neither of these theories has to date been scientifically verified.

Chicken breeds recognized by the American Poultry Association China; they are large, feather legged, and lay brown eggs: This group consists of eleven breeds from Belgium, France, Germany, and the Netherlands. They are mostly sprightly birds, the Faverolles being an exception: This class consists of five breeds from the United Kingdom and one from Australia: These breeds originating in Italy and Spain have white earlobes and tend to be productive layers of white eggs. In general they are flighty, and exceptional free-range birds, with both evasion and foraging skills: Other breeds ae grouped in this class, which has three subclasses: Game, Oriental, and Miscellaneous.
