SMALL INCUBATOR HOUSES 



20— GROUND PLAN FOR LARGE INCUBATOR CELLAR 



Incubator houses are best made in half cellars, and when 

 possible should be put up early in the season on dry, high ground. 



It is often desirable to hatch late in the spring or even in 

 the s umm er, and a house entirely above ground then gets too 

 warm for the best work. With a half cellar the air strikes the 

 walls, which the outer ground keeps cool, and the temperature 

 can be kept down to 60 or 65 degrees, excepting in the very 

 warmest weather. A row of windows is placed on either side 



19— SECTIONAL VIEW OF SINGLE INCUBATOR CELLAR 



well up toward the ceiling, so that a window can be opened on 

 either side of the house to afford ventilation without a draught 

 striking the machines. 



In 111. 19 we present a sectional view of a single incubator 

 cellar which can be made to hold from six to twelve or four- 

 teen incubators. 111. 17 shows the ground plan arranged for 

 ten large incubators. The house should be 12 feet 6 inches in 

 the clear on the inside by 25 feet in length. If it is desirable to put 

 up a house for only six incubators it will need to be only 15 feet 

 in length. A large incubator practically takes up 5 feet of room. 



The incubator house should set 3 feet in the ground 'with 

 a 2 foot banked wall above, making 5 feet in all under ground. 



There should be 8 feet head room from the floor to the plates 

 or ceiling. Do not build a lower ceiling, as a lower room will 

 not give sufficient cubic feet of air space to allow the air to be 

 kept fresh.
