24 Money in Broilers and Squabs. 



If the temperature gets too high, the hatch will come off before 

 it is due; and if too low, the hatch wiTi be delayed several days. 

 Either extreme is detrimental to the streng>ih of the chicks. 



Never add eggs to the incubator after 'you have started the 

 hatch. 



Be careful that the flame of the lamp is not turned up so high 

 that it will smoke. In this way soot is gathered and very often the 

 machine is set on fire. 



Make a study of the air cells, and govern the treatment accord- 

 ing to their size. 



In placing the eggs in the incubator, see that the large eggs are 

 all pointing the same way in the trays. 



Sometimes a delayed hatch can be hastened by placing sponges, 

 dipped in boiling water, in the machine. 



After the fourth day the eggs can be cooled, doing so only a 

 little at first, and longer as the hatch progresses. 



If the air cell of the egg is very large, add moisture, and if very 

 small, take away what water you have in the pans. 



After the eighteenth day, do not turn nor cool the hens' eggs. 



The air cell on the fifth day should measure about a quarter of 

 an inch ; tenth day, half an inch ; fifteenth day, five-eighths inch ; 

 nineteenth day, three-quarters inch. Take measurement from mid- 

 dle of large end. 



Chilled eggs will not hatch. 



Be sure that your thermometer is correct. Nothing will do as 

 deadly work as an inaccurate thermometer. 



Likewise see that the regulator really regulates. We have 

 seen quite a number of regulators that needed regulating very badly. 



"Eternal vigilance" should be the watchword. There are so 

 many little details in this work, that unless you give it the closest 

 attention you will have trouble which is not so readily adjusted. 

 The successful broiler raisers of to-day are those who "stick to the 

 ship" from beginning to end. 



We have little or no faith in hygrometers or moisture gauges. 



After each hatch, see that the incubator is thoroughly cleaned 

 and fumigated. 



To get the correct temperature of the tgg chamber, see that 

 the bulb of the thermometer rests upon a strong fertile egg. 



While you are cooling or turning the eggs, keep the incubator 

 doors closed. Do not try to hatch duck eggs and hen eggs in the 

 same machine at the same time. The conditions for each are dif- 

 ferent. Neither place eggs of different varieties in the machine at 

 the same time. A mixture of white and brown shelled eggs will 

 give unsatisfactory hatches, for the reason that the brown shelled 

 egg is a much harder shell and requires different treatment than 

 does a white shelled one. 



Before you start the incubators in the house cellar, consult your 

 insurance policy. Ten chances to one, there is a prohibitory clause 

 in it which would cost you your insurance. 



Keep a record from the time you start the incubator until the
