The Yurlov crower is an old breed of domestic chicken that was developed in Russia during the second half of the nineteenth-century. It was most likely developed by the breeding of land race chickens, fighting chickens, and Chinese breeds. During the twentieth-century, the breed was highly popular, but it declined in number when the area was known as the USSR and as the Independent Russian Federation, as well as Ukraine, reaching an estimated number of only 200 by 1995. However, the current population in these areas is thought to be in the thousands and it is growing in popularity in many European regions. It can come in a variety of colors including black, white, scarlet, and silver.
