=Weight.=--There is no standard weight given for Black East Indians; the smaller their size the higher they rank for exhibition purposes. CRESTED WHITE DUCKS. _History._--The Crested White duck (fig. 8) is what may be called an ornamental duck, much the same as Polish chickens. They are not bred to any great extent in this country, and they are very seldom seen in the showrooms. They have no especial value to the farmer, as better and more easily-bred birds are to be found in the Pekin and Aylesbury. [Illustration: Fig. 8.--Pair of Crested White ducks.] =Description.=--These ducks have a medium-sized head; medium-sized bill; a large, well-balanced crest upon the crown of the head; a rather long neck; a medium-length back; breast, round and full; body, round and of medium length; medium-length wings that smoothly fold; hard, stiff tail feathers, with well-curled feathers in the tail of drake; and short and stout thighs and shanks. Their eyes are large and bright and of a deep leaden blue or gray color. The shanks, toes, and webs are of a light-orange color. =Weight.=--The standard weight of the adult drake is 7 pounds; adult duck, 6 pounds; young drake, 6 pounds, and young duck, 5 pounds. MANAGEMENT OF DUCKS. Duck raising has been developed within the last ten years into a flourishing industry. Prior to that time the duck was not considered a profitable fowl to raise; its flesh was never prized very highly by the masses. Ducks were raised without constraint in waterways, feeding mostly on fish and water insects. This food gave the flesh a strong fishy flavor; hence it was not particularly sought after, save by the few who were partial to that class of diet. The duck centers of Long Island and New England were then producing a limited number each season, and it was with difficulty that these were sold with any profit. In fact, one of the most prominent duck raisers may be quoted as saying that he was obliged to visit the city markets personally and tease the dealers to purchase his birds, in order to secure anything like satisfactory prices. Artificial incubation and brooding, combined with judicious feeding, have been instrumental in the development of the industry. Machinery has enabled the duck raiser to accomplish his ambition of having his stock in the markets when prices are the best, and also of raising large numbers of birds in a limited space of time. The season for raising ducks is about six months--from February to July. The methods employed by the most successful raisers will be given in this bulletin, and the most approved buildings, appliances, feeding, and care will be treated in detail.
