is for incubators and brooder houses. If the duck
farmer now tries to add broilers, he will find that the labor comes
at the same time of the year, that the chief equipment required is
that which is already crowded by the duck business, and that of the
men who have succeeded moderately well in caring for ducks will fail
altogether with the young chicks, which do not thrive under the same
machine-like methods.

On the other hand, let us take the example of an egg farm man who
has resolved to combine his attention wholly to the production of
market eggs. He succeeds well in his work and is visited by the
poultry editors. His picture, the picture of his chickens and of his
chicken houses, are printed in the poultry papers. For a reasonable
sum invested in advertising and in exhibition at the shows, this man
could now double his income by going into the breeding stock
business. To refuse to spread out in this case would certainly be
foolish.

The following classification of the sales products of the poultry
industry is given as a basis for farther consideration.

CHICKENS.

For food purposes:

Eggs.
Hens, after laying has been finished.
Cockerels, necessarily hatched in hatching pullets for layers.
(Sold as squab broilers, regular broilers, springs,
roasters or capons.)
Both sexes as squab broilers, broilers or roasters.

For stock purposes:
Eggs for hatching.
Day-old chicks.
Mature fowls.

DUCKS.

For table--green or spring ducks.
By-products, old ducks and duck feathers.

For breeding-stock.

GEESE.

Food, Feathers, Breeders.

TURKEYS.

Food, Breeders.

PIGEONS.

Squabs, Breeding Stock.

GUINEAS.

Broilers, Mature Fowls.

I will now discuss these products more in detail. Poultry, other
than chickens, I do not care to discuss at length, because it is not
for the purpose of the book, and because the demand for other kinds
of poultry is limited and the chance for the growth of the business
small.

The Duck Business.

The duck business is the most highly commercialized at the present
time of any branch of the poultry business. The duck is the oldest
domestic bird and was hatched by artificial incubation in China,
when our ancestors were gnawing raw bones in the caves of Europe.
