That man was promptly discharged, and I undertook the feeding myself. The birds were sorted out and returned to their own yards, the wire replaced, the feeding-troughs cleaned, the pens carefully disinfected. In four days double the amount of food was consumed and things were decidedly improved. But those birds never acquired that uniformity of size and appearance which had always characterized my market birds. The best material to use in the pens inside the brooding-house is dry, fine sawdust, if it can be obtained. It is by far the best thing I know of for the purpose. The next best is finely chopped straw or hay, tanbark, etc. The brooders, like the pens, require close attention. The top should be scraped off before it becomes offensive, and new material applied. This can be easily done by simply lifting the edge of the cover next the walk and drawing it over into the walk, when it can be taken in a barrow or basket. The Necessity of Green Food. It must be remembered that as the broods grow older the cleaning process must be repeated oftener, as their capacity for generating filth will always be in proportion to their size. Those unacquainted with duck-culture have little idea how fast these birds will grow; how soon they will successively outgrow brooders, pens and yards, and how soon every vestige of green will disappear from yards that were thickly covered with rye. But the ducklings must be kept growing at all hazards, and a vegetable supply must be procured from outside. [Illustration: WEST SIDE OF LANE.] Rye comes first in the season (I always cultivate it for the purpose, and when coarse, it must be cut so that it can be readily eaten); then grass; and next corn fodder, which is best of all. It is astonishing how much of the latter these birds will consume--hundreds of pounds each day. It should be cut very fine, not more than one-third of an inch in length. Unlike the hen, the birds prefer the stalk to the leaf. Give them all they will eat, once each day. [But we have forgotten that empty machine. After the ducklings are taken out it will be found running at 85 to 90 degrees. I gauge it up to 102 and fill it with fresh eggs at once, not forgetting to fill one tray in the little tender.] There is one bad habit to which ducklings of four or five weeks old are addicted, and that is feather eating. First the down will begin to disappear from their backs; next, as the birds grow older, the quills which grow out from the end of the wings will disappear, and they are all exposed for tempting morsels.
