BROODING 



105 



FIG. 7 



It is quite difficult to have both heat and ventilation if 



25 or 30 chicks are shut up in a box of this kind. They 



will keep warm enough 



to live, but without 



ventilation they will 



die. 



Temperature for 

 Brooders. Proper 

 warmth is of prime im- 

 portance in artificial 

 .brooding. If the chicks 

 are chilled, they are of little value thereafter; if over- 

 heated, they lose vitality. The frequent occurrence of 

 either chilling or overheating or both will destroy 

 an entire lot of chicks. A temperature of about 105 F. 

 does not injure the young chicks half as much as a 

 temperature of 60 F. A chill causes indigestion, loss 

 of appetite, and bowel trouble, from which the chick 

 seldom or never recovers. The proper degree of heat 

 should be maintained with absolute regularity, and 

 there should be none but the slightest change of 

 temperature inside the brooder. 



The temperature inside the brooder beneath the hover 

 where the chicks go to keep warm should be 90 F., 

 during the first 7 da. This temperature should be re- 

 duced a little each day thereafter until the temperature 

 is 80 F. beneath the hover. This is the correct tem- 

 perature for the young chicks; if the chicks are warmer 

 than this they suffer from the heat; if the temperature 

 is less, the chicks are chilled and ailments result. With 

 this temperature beneath the hover, the nursery should 

 be about 70 F. The chicks come from the nursery of 

 the incubator where the heat is about 95 F. and at first 

 they should have the same degree of heat in the hover. 



Securing of Proper Temperature. The lamp for the 

 brooder should be large enough to hold sufficient oil for 

 1 day's burning. It must be strongly made of heavy 

 metal, so that it will stand rough usage. The wick 

 in the lamp must be long, and both the wick and the
