The Polish or Poland is a European breed of crested chickens known for its remarkable crest of feathers. The oldest accounts of these birds come from The Netherlands; their exact origins are unknown, however. In addition to combs, they are adorned with large crests that nearly cover the entirety of the head. This crest limits their vision, and as a result can affect their temperament. Thus, though normally tame, they may be timid and easily frightened.
Though the derivation of the Polish breed is unclear, one theory suggests that their ancestors were brought by Asian Mongols to Central and Eastern Europe during medieval times, and thus, could have originated in Poland.
