QUESTION If eggs do not hatch at the end of the 2ist day is it 

 worth while to keep them longer? 

 ANSWER No. 



QUESTION Will a very slightly cracked egg hatch? 

 ANSWER Sometimes they will. 



QUESTION What causes the temperature in the incubator to 

 fall one to two degrees when the chicks are hatching, and should the 

 lamp be turned up at that time to increase the heat? 



ANSWER This condition is usually found in machines where 

 the wet chicks come in contact with the bulb of the thermometer and 

 the natural result is a difference in the register. It is desirable to 

 maintain 103 degrees in the machine at this time and there really is 

 that amount of heat. Under the circumstances, the lamp should not 

 be changed. 



QUESTION Is there any one incubator better than another for 

 a beginner to start with?

 could be better for the novice it would also be better for the expert.

 it should never come out. 



QUESTION If an incubator is being run in a cellar which on 

 account of heavy rains becomes filled with water nearly to the bottom 

 of the lamp, is it worth while to continue the hatch? Will not so 

 much dampness injure the hatch ? 



ANSWER Good hatches have been brought off under these con- 

 ditions and in such cases the machine should not be neglected. 



QUESTION What are addled eggs? 



ANSWER Those in which the germ has died during incubation 

 before the embryo is well formed. 



QUESTION Do incubator chicks have to be taught to eat ? 

 ANSWER Only by placing the food before them at the proper 

 time. 



QUESTION Is there any danger from fire in running an incu- 

 bator in the dwelling? 



ANSWER No more than there would be in having an ordinary 

 house lamp burning and in most cases not as much.
