Hatching with Incubators 127 



like this for running an incubator. Manufacturers 

 send instructions for assembling and handling 

 their machines which are compiled after a long 

 series of experiments with that particular machine, 

 and each detail is covered with minute care. In 

 running the machine follow the printed instruc- 

 tions that deal with that particular incubator, and 

 you probably will have no difficulty. 



There are, however, general rules that apply 

 to all incubators which should be followed. The 

 inside of the machine and egg compartments 

 must be thoroughly cleansed before each hatch. 

 Hot water and soap, with a coal tar disinfect- 

 ant, may be used as a wash, or the washing may 

 be with soapsuds, and a spray used afterward. 

 Many who run large incubators spray the egg 

 chambers during the hatch while the eggs are out 

 cooling. 



Level the machine with care before the eggs are 

 'put in place. Hot air and hot water tend to 

 rise to the upper comer, and if there is a slope 

 the eggs near the top will be much warmer than 

 those at the bottom. If the egg tray is exactly 

 level all the eggs will have the same degree of heat. 



Fill, trim, and regulate the lamp in the morning.
