_Feeding the Ducklings._ Ducklings do not need to be fed until they are from 24 to 36 hours old. At this time they may be given a mixture composed of equal parts by measure of rolled oats and bread crumbs with 3% of sharp sand mixed in the feed. This may be given them five times daily although some duck raisers feed only 3 times daily from the start. About the third day this feed is changed to equal parts of bread, rolled oats, bran and corn meal. After the seventh day the ration may consist of 3 parts bran, 1 part each of low-grade wheat flour and corn meal, 10% green feed, 5% beef scrap with about 3% of sand mixed in. The ducklings should be fed four times daily after the seventh day until they are two or three weeks old. After that time they need be fed only three times daily, morning, noon and night. The sand may be given to the ducklings either by mixing it in the mash or by feeding it in a hopper where they can help themselves. The mash feed which is prepared for the ducklings is mixed with water until it has a consistency a little wetter than crumbly but not exactly sticky. Sloppy feed should never be used. As the ducklings grow older the amount of beef scrap can be increased until it consists of 15% of the ration by the end of the third week. The proportion of corn meal can likewise be increased and simultaneously the amount of bran decreased until the ducklings are on a fattening ration. Unless they have a plentiful supply of green feed in the yards to which they have access it is necessary to provide this to the extent of about 10% of the feed and it should consist of tender green stuff rather finely chopped and mixed in with the mash. About 2 weeks before the ducklings are to be marketed they should be put on a ration consisting of three parts by weight of corn meal, two parts low-grade flour or middlings, one part bran, one-half part beef scrap, 10% green feed and about 3% oyster shell or sand. This mash is fed three times daily. Another ration which can be used for fattening purposes consists of 3 parts corn meal, 1 part low-grade wheat flour, 1 part bran, 5% beef scrap and 3% oyster shell with green feed and grit in addition. Where fish is available it can be substituted for the beef scrap but on most farms this is impractical. The fish where fed is boiled and mixed in the mash. However, no fish should be fed up to within 2 weeks before the ducks are killed as there is danger of giving a fishy taste to the carcass. For additional information as to feeding methods used on commercial duck farms which could be utilized to advantage for the farm flocks, see Chapter VI. Birds which are to be reserved for breeders should be selected out and taken away from the ducklings which are to be fattened. These breeding birds should be carried along on the ration which they have been receiving until about December 1 when they should be put on a laying ration.
