II. By having the chick floor elevated, the 

 chicks are brought nearer the ceiUng, which is 

 the warm part of the house; this reduces the 

 enclosed air space, which means a saving of heat 

 required to maintain a given temperature. 



If a pipe brooder house, examine the con- 

 struction of the hover. Are the pipes carried 

 through the top of the hovers, supplying heat 

 from above, or are the pipes carried under the

 for ventilation. Is the building supplied with
