piece of tin. In the center of the floor, underneath the tin 

 tack a tin bucket-top in which to place the lamp. The tin 

 top will prevent the lamp from being misplaced underneath. 

 With a brace and bit bore three 1-inch holes in the brooder, 

 in places where shown in Fig. 169. Bore the middle row be- 

 tween the piece of tin and the middle floor. 



Cut the two openings in the front 5 by 6 inches, and cut one 

 in the partition the same size, over which tack a piece of woolen 

 cloth, in which cut two or three slits. Make an opening in the 

 left end of the brooder 5 by 10 inches, over which tack a piece 

 of wire cloth. 



The cost of the material and lamp is about $3.50.

CONSTRUCTION OF THE FIRELESS BROODER 



The fireless brooder is a success in the later spring and 

 summer, when the outside temperature is not so cold, or after 

 the chicks have been in a heated brooder for a considerable 

 time and gradually brought down to only their own heat 

 produced by their bodies. 



This system requires that several chickens be placed together, 

 as the source of heat is solely from their bodies, and keeping 

 them warm depends upon the conservation of this heat.
