They are then fed on equal parts of corn meal, wheat-bran and low-grade flour, with about twelve or fifteen per cent. of animal food. One fourth of this food should be composed of vegetables cooked--say, small potatoes, turnips, etc., with all the green rye and refuse cabbage they will eat. We feed this compound morning and evening with a little corn, wheat and oats at noon. Feed all the birds will eat clean and no more. The birds, young and old, may be expected to lay in three weeks from the time they are housed. This part of the thing seems to be under perfect control. You turn in the proper variety of food and they cannot help turning out a generous supply of eggs. The fertility however, cannot, at this season of the year be so perfectly controlled, as the standard of fertility in the first eggs is apt to be very low, but soon comes to a high point. The fecundity of these birds is wonderful. As a general thing each bird can be depended upon for 140 eggs each season, and as the eggs always command from 5 to 10 cents per dozen more than those from hens it makes the Pekin ducks more profitable for eggs alone than any other fowl. Incubators. With the necessary buildings constructed and the stock selected, the next thing required is the incubator, for I do not suppose the modern poultry grower is going to do his incubating with hens, for the simple reason that he cannot afford to. Hens show no desire to incubate when you want them to the most, or in time to command the high prices for ducks and chicks in the early spring, and this is attended with a loss of at least one-half of the season's profits. I often have letters filled with questions concerning incubators. Which is the best incubator? Can a person of ordinary intelligence run one successfully? Do they require watching during the night? Is there an incubator in the market today that will hatch as well as the average hen? and many more of like import. To the first I would say that modesty forbids a candid answer. There are objections to many machines, though the same do not apply to all. It does not become me to mention their failings. But first of all do not buy a cheap incubator, as the conditions to which the material of an incubator is exposed are of the severest kind. It must be exposed constantly to a temperature of 103 degrees, and that in an atmosphere surcharged with moisture; and unless the material of which the machine is constructed is of the choicest kind, well kiln-dried and put together, the chances are that it will warp out of shape, admit drafts of air and injure, if not destroy, the regulation.
