A one-inch mesh wire floor supported on a metal ring and framework, with 

 inclined ramps is shown (above) and as placed under a brooder (belbw). 

 Quarter-inch mesh was placed over the one-inch until the chicks grew to size. 



the principal problems has been to determine how the outside tempera- 

 ture influences the floor temperatures. Supported by the investiga- 

 tional work already recorded, this study was an attempt to show the 

 principal factors in the control of erratic changes of temperature in the 

 lower stratum of air under brooders, and on the floor and litter. 



Raised Wire Mesh Floors 



A comparison of the curves discloses that the use of the elevated 

 wire-mesh floor (Fig. 7) made no significant change in the character 

 of the floor temperature curve,* other than to flatten its tops somewhat 



* The thermometer bulb rested on the wire mesh.
