Feeding. The feeding of ducks differs from the feeding of hens in that ducks need mostly soft food, and that, if the keeper wishes to force growth or egg production, they may be fed much larger proportions of such concentrated foods as beef scraps and meat meals. As has been stated, in its natural state the duck gets the greater part of its food from the water. This is all soft food, and the bird swallows a great deal of water with it. It does not, therefore, need a large crop in which to soak its food before it passes into the gizzard. So the crop of the duck is small—merely an enlargement of the gullet. Some of the old books on poultry say that the duck has no crop, but you can see by looking at a duck that has just had a full meal that the food it has taken remains in the passage, sometimes filling it right up to the throat.

With a mash (just the same as is given to hens) morning and evening, a cabbage to pick at, plenty of drinking water, and a supply of oyster shell always before them, ducks will do very well. If they have no cabbage, about one third (by bulk) of the mash should be cut clover or alfalfa. When the days are long, it is a good plan to give them a little cracked corn or whole wheat about noon. The water supply should always be replenished just before feeding, for as soon as a duck has taken a few mouthfuls of food of any kind, it wants a drink of water.
Laying habits. With the exception of the ducks of the Indian Runner type, which lay some eggs at other seasons, as hens do, ducks usually lay very persistently for about six months, and then stop entirely for about six months. Occasionally ducks of other breeds lay a few eggs in the autumn, but this trait has not been developed in them as it has in the Indian Runner. If they are comfortably housed and well fed, Pekin and Rouen Ducks usually begin to lay in January. If they are allowed to expose themselves to rough weather, and are fed indifferently, they may not begin to lay until March or April. When they do begin, they usually lay much more steadily than hens until hot weather comes, and then gradually decrease their production until by midsummer they have stopped altogether.

The eggs are usually laid very early in the morning. Ducks often lay before daylight and almost always lay before eight o'clock. When a duck lays in a nest, she is very likely to cover the egg with the nest material when she leaves it. A duck will often make a nest and remain on it an hour or more and then go and drop her egg somewhere else and pay no further attention to it.
