CHAPTER XIV. 



How to build an ideal incubator house. 



I have told you in my former chapters how to 

 produce your eggs in the greatest possible number and 

 how to produce eggs that will give you the largest 

 hatches. Now you will want to know how to hatch 

 them. First, I will tell you how to build what I con- 

 sider the most perfect incubator house. Select a side 

 hill if you have one near by, for a perfect incubator 

 house should be part under ground and part on top. 

 You can determine size of house by the number of 

 machines you want to use and the number of chicks 

 you wish to hatch. But it is always safer to build 

 much larger than your present needs, then you will 

 not have to rebuild or enlarge when your business 

 grows. 



To build this house, put up a wall of stone, five 

 feet high on all four sides, putting in windows at the 

 top of your wall a four pane window, 8xio glass, will 

 answer the purpose nicely. Hinge at bottom so it will 

 open inside. 



Put windows on each side and at south end. Put 

 none on north side. A window every ten feet is about 

 right. Now put a window in each end for ventilation. 

 Put these windows near peak, a six light window; 

 8xio glass, and in summer these can be left open for 

 ventilation. This makes an ideal incubator house. 



Throw up dirt to top of wall on all sides, except 

 South end, and put in a double door wide enough to 

 carry out any incubator set up. 



The air in such a house always smells free from 

 lamp smoke and if you fail to get good hatches in 

 such a house you will know it is not the fault of the 

 house.
