_Equipment, Capital, etc. Required._ The estimates given as to the amount of equipment and capital required are based on the assumption that a plant is to be operated of sufficient size to have a yearly output of about 30,000 ducklings. It must be understood in this connection that location and various other conditions or circumstances will influence the cost of different items of equipment and for this reason these estimates must not be considered as absolute but should rather serve as a guide or basis on which to figure. The figures here given contemplate the building up of an establishment which is efficient but which is in no particular elaborate, the buildings and other equipment being as simple and inexpensive as possible. _Lay-out or Arrangement of the Plant._ The plant must be carefully planned so as to make the best possible use of the land and particularly of the water frontage. It is particularly important to arrange the buildings in such a manner as to cut down labor as much as possible. If there is any expectation of enlarging the capacity at some future time, this must also be borne in mind in the arrangement of the various buildings and yards. The incubator cellar should be convenient to the No. 1 brooder house and the various brooder houses to one another. The brooder house must likewise be convenient to the growing and fattening houses and yards and these in turn to the killing house. The feed room should be centrally located so as to save labor as much as possible in feeding the ducks. _Land Required._ For a duck plant of the size indicated 10 acres of land should be ample. This, however, means that no effort would be made to grow any of the feed for the ducks or ducklings with the exception of green feed. In some cases where the lay of the land is unusually favorable so that the plant can be laid out to the very best advantage, a smaller amount of ground than this might be sufficient but it is not well to figure on less than 10 acres. _Number of Breeders Required._ With the usual methods of management and with good success, one may estimate that 40 young ducks can be marketed each year from each breeding female. This is a good average although in some good years duck raisers will do a little better than this. On the other hand in poor years they will not do so well. For a plant having an output of 30,000 market ducks there would therefore be needed in the neighborhood of 800 breeding ducks in addition to 100 drakes.
