Figr. 17. A portable "A" shaped colony house 



This is a type of house used at the Experiment Station as a 

 brooder for 200 chicks in the spring, as a colony house during the 

 summer, and a laying house during the fall and winter. It is 

 placed on runners, and is easily moved. A colony brooder is the 

 only type that can be used the year round, thus overcoming the 

 common practice of having idle brooders eight months of the year. 



This particular type of "A" shaped brooder is heated with 

 gasoline, the hover and heating apparatus having been designed at 

 Cornell University. 



The Colony brooder is the cheapest brooder that can be built, 

 saves much labor, and if heated by gasoline is the only brooder 

 that supplies fresh air directly under the hover. The house can 

 be moved from place to place and roosts put in when the hover is 

 removed. This house is 8 x 8 feet square and 6]/ 2 feet high from 

 floor to comb. It is not economical to use this size colony brooder 

 where less than 150 chicks are brooded at once.
