Except for what are called (perhaps erroneously) low-temperature ^ hens, the temperature in natural brooding, with suitable-sized broods, is never injuriously wrong. The regulation of temperature is automatic and nearly perfect. Regulation of heat in artificial brooding. The operation of a brooder presents problems similar to the problems of artificial in- cubation. The general problem is to provide a substitute for the heat of the parent bird. It is economically necessary that this be done at a cost for equipment and labor that will leave a profit on the work. While it is not required that a uniform temperature be as steadily maintained as in incubation, the artificial brooder must be in a measure auto- matically regulating for temperature, and fresh air must be supplied to the young birds in the hover in much larger quantities than to the eggs in the egg chamber of the incubator. The difficult point is to secure free ventilation while maintaining a sufficiently high temperature. This is commonly made more difficult in practice through the tendency of poultry- men to economize capital, space, and labor by putting into each brooder compartment the largest number of chicks or ducklings that it is considered possible to keep in it.
