Hot-Water System.—The earliest method of heating the hovers in a long brooder house was by means of a series of hot-water pipes arranged about eight inches above the floor of the brooder. The chicks huddled together under these pipes, and ventilation was controlled by means of apertures in the tops of the hovers. A development of this idea was found by heating a compartment.

Fireless Brooders.—Another method is to heat the brooder house to a moderate temperature by the use of a few coils of hot- water pipes, but to heat the hovers themselves by means of indi- vidual kerosene lamps. An adaptation of this method is to use fireless hovers, so constructed as to conserve the heat thrown off from the chicks' bodies. See Fig. 195. These fireless brooders.
