POULTRY LABORATORY GUIDE 21 



What kind of material is used for the floor? 

 Cement is best. Why? 



Note carefully the method of construction as 

 regards the shape of the building, type of roof, 

 lumber used, and whether double or single walls. 

 Is there any provision made for regulating the 

 temperature of the cellar? The most desirable 

 temperature is from fifty to seventy degrees, but 

 incubation may be successfully carried on in a 

 temperature of thirty-five degrees, the disadvan- 

 tage being more in rapid variation than in a too 

 high or too low general temperature. 



Connected with the incubator cellar there 

 should be a small room which is easily darkened 

 for the testing of eggs during incubation. The 

 presence of shelves or tables conveniently located 

 should be noted — one upon which all surplus 

 lamps are kept and where all trimming and filling 

 are done; another one should be for the turning 

 and cooling of eggs. A closet or shelves for the 

 keeping of thermometers, hygrometers, incubator 

 parts, records, etc., is very essential. The pres- 

 ence of a faucet from which water can be taken 

 to increase the humidity of the room is very 

 desirable. 



Estimate carefully the probable cost of such a 

 building or room, also figure the capacity of the 

 cellar in dozens of eggs and determine the cost
