Previous to this our oldest ducklings will have reached the extreme end of the brooding-house, and it will be filled to its utmost capacity. In order to make room for the successive hatches I drive the older hatches out and round to my cold buildings, two in number. These buildings are each seventy-five feet long, with contiguous yards one hundred feet deep. The slides in the buildings are left open, and the ducklings are at liberty to go out or in as they see fit,--a privilege of which they avail themselves as the state of the atmosphere inclines. These yards always have a thick mat of rye growing on them. The partition wires have been set up and the young birds are quietly driven to their respective quarters. After ducklings reach the age of six weeks, it is not necessary to confine them in buildings during the night. Indeed, they are far better not, unless it is extremely cold, or there is danger from vermin. Even severe rainstorms will not injure them. They should be watched carefully, however, as they are apt, during their antics, to fall over on their backs, when, through suction from the wet and muddy ground, they are seldom able to turn back again. Prompt assistance should be rendered, or it will surely be too late, as the back of a duckling is his most susceptible part. After the birds are six weeks old it will not be necessary to feed more than three times per day, gradually substituting meal for bran, until the birds are eight weeks old, when their food should be, at least, three-quarters meal. There should also be a steady increase of animal food after the seventh week. Careful Watering Even More Essential Than Food. Particular care should be taken at this time to give the birds all they need to drink, or your food will be thrown away, as they require more water during the warm weather. They will consume and waste vast quantities, and the water supply should be made as convenient as possible, to facilitate the business. Our water is forced by a windmill into a two hundred-barrel tank, and leads from there through pipes into brooding and breeding houses, into the yards and mixing room,--all with a view to saving labor and time. The water-pans in the buildings are raised six or eight inches from the ground to prevent the birds getting in or wasting the water.
