Anotations

Scope note:

Heated structures used for raising young fowl, traditionally wood-framed, wood-floored, movable structures heated by electric or oil-fired stoves and built on skids. The chicks are housed from hatching until they are about six weeks old, when they no longer need heat. Commercial brooder houses may be very large, having several brooder units, underfloor heat or heat lamps, fan ventilation, automatic waterers and feeders, and large doors through which tractors and litter-removing equipment can pass.
