Duck raising while representing an industry of considerable value to the United States when considered from a national standpoint, is one of the minor branches of the poultry industry. According to the 1920 census there were 2,817,624 ducks in the United States with a valuation of $3,373,966. As compared with this the census for 1910 shows a slightly greater number of ducks, 2,906,525, but their value was considerably less being only $1,567,164. In the ten years between the census of 1900 and that of 1910 there was a decrease in the number of ducks of nearly 40%.
