IBrooding is the art and science of rearing baby chicks. A newly hatched chick does not develop the thermoregulatory mechanism fully and takes about two weeks to develop this mechanism and homeostasis. Therefore, they cannot maintain the body temperature properly for the first few weeks of life; and may be subjected to chilling, if not properly taking care of. Brooding can be classified into natural and artificial brooding.
  Natural  brooding
  It is done with the  help of broody hens after hatching, up to 3 to 4 weeks of age.
  Artificial  brooding
            In artificial  brooding large number of baby chicks are reared in the absence of broody  hen.  Equipments used for brooding are  called brooders.  Brooder comprises of  three elements:
Heating source may be electrical, gases like natural gas, LPG and methane, liquid fuel like kerosene, solid fuel like coal, wood can be used as a heating material.
  1)  Charcoal stove / kerosene stove:

  Where electricity  is not available, ordinary charcoal / kerosene stoves are used to provide  supplementary heat to chicks.  These  stoves are covered with plate / pans to dissipate the heat.
  2)  Gas brooder:

  Natural gas, LPG or  methane is connected to heating element which is hanged 3 to 5 feet above the  chick to provide heat.
  3)  Electrical brooder:

  It is also  thermostatically controlled heating system that spread required amount of heat  uniformly above large area, this avoid crowding of chicks under brooder  directly.  One electrical brooder can be  used for 300 to 400 chicks.
  4)  Infra-red bulbs:

  It is a self  reflecting bulb.  One 250 watts IR bulb  can provide brooding for about 150 to 250 chicks.
  5)  Reflectors:

  These reflectors  are called Hovers.  Flat type hover –  These hovers are provided with heating element, heating mechanism and pilot  lamp and in some cases thermometer is also there in order to record the  temperature. Canopy type hover – These reflectors are in concave shape consisting  of ordinary electrical bulb, thermostat mechanism and in some cases  thermometer.
  6)  Brooder guard / chick guard

  They are used to  prevent chicks from straying too far away from heat supply until they learn the  source of heat.  We have to provide  brooder guard with a diameter of 5 feet, height of the brooder should not  exceed 1.5 feet.  For this purpose, we  can use materials like cardboard sheet, GI sheet, wire mesh, and mat etc.  depending upon the season of brooding.   During winter season, brooding is done for 5-6 days.  In summer season it is 2-3 weeks.
