Answer:

An incubator is a desirable addition to the poultryman's plant, whether he has many or few fowls.

Machines of small capacity may be purchased cheaply and they are always ready for service.

With them, eggs may be hatched at any season of the year; one does not have to depend upon sitting hens, and eggs hatched in an incubator do not produce chicks covered with lice as is the case when hatched by hens.
