BROILERS AND ROASTERS. 49 



Another plan which seemed to please, for at least a time, 

 the few who used it, but has never found favor generally, 

 was to elevate the brooders two feet or more from the 

 floor and build small pens, practically boxes, on the same 

 level for the chicks to run in, there being passage room in 

 the front of the house as well as in the rear. This was 

 only used in "nursery" brooder houses for very young 

 chicks. 



Individual brooders have not, as a rule, been used on 

 large plants, except as "nursery" brooders in which the 

 chicks were put when taken from the incubators, and kept 

 only for the few weeks when they were most dependent 

 upon artificial heat maintained at a nearly uniform and 

 relatively high temperature. On some large plants an 

 entire building is used in this way as a nursery brooder 

 house. More frequently one wing of a long brooder house 

 is used as a " nursery " with individual brooders, while the 

 other wing has pipe brooders, and into this the chicks are 

 put as soon as they are able to stand lower temperatures 

 and wider fluctuations of temperature. For some years 

 this arrangement was very popular, and though it is still 

 perhaps more common to find it than the exclusive pipe 

 system, the latter as now generally put in with ample 

 heating capacity and electric regulating attachment seems 

 to give better satisfaction. 



28. Individual Brooders in Small Houses For 



single pen brooder houses, and for houses of only a few- 

 pens, individual indoor brooders are very generally used. 

 A common practice is to use an indoor brooder in a large 

 coop or small house, from which the brooder can be 

 removed when the chicks no longer need it. This arrange-
