wire about a foot from the floor, allowing the 

 work to be done from the walk by simply re- 

 moving or raising the wire frame ? The latter 

 method is adapted for young chicks and espe- 

 cially where individual brooders are used. 



Figure the total square inches under the hovers, 

 also the total square inches of chick floor space 

 in the whole house, and determine the capacity. 

 Each chick requires about four to five square 

 inches of hover space the first week, which 

 amount should gradually increase until at six 

 to eight weeks of age they require from ten to 

 twelve square inches of hover space. The idea 

 is to give them sufficient room to spread out and 

 not to crowd. 



Is the heater located in the centre of the 

 brooder house or at the end ? If the runs of the 

 pipe are to be over one hundred feet, the heater 

 will prove more efficient if placed in the centre 

 with the runs of pipes running each way; if less 

 than one hundred feet, it is best placed at the 

 end of the house.
