Hatching with Incubators 151 



will be in the same position as it was before. By 

 passing the hands over the tops of the eggs we 

 may roU them together into the new positions, and 

 may roll them back again at evening with equal 

 ease. Large machines have special arrangements 

 for turning. 



See that the lamp is filled and regulated every 

 morning. Take no chances toward the end of the 

 hatch even if little oil is burned out. It may last 

 forty-eight hotirs and it may not. 



Watch the thermometer, to make sure that it is 

 not touching the eggs, and keeps its position at 

 about the level of the eggs throughout the hatch. 



Cool the eggs if you feel that you wish to do so, 

 but remember that the best opinion to-day consid- 

 ers that this will not increase the hatch. 



Test the eggs about the sixth day. Remove all 

 infertile eggs, and those where the germs have died. 



After this, during the second week, the temper- 

 ature will rise, and a smaller flame may be required. 

 Regulate the thermostat, and keep the ther- 

 mometer at about 102 degrees. 



The third week the body heat of the chicks will 

 be still greater. Watch the thermometer and keep 

 the temperature the third week at 103 degrees.
