POULTRY-HOUSE CONSTRUCTION. 



Plans are usually given by brooder-manufacturers to persons desirous of using 

 the oil-burning stoves. 



CONSTRUCTION OF FRESH-AIR BROODERS. 



The problem of securing better results from brooding has been studied and experi- 

 mented with by many different experiment stations and individuals for several 

 seasons past. There have been so many difficulties to contend with that the work 

 has been left mainly in the hands of communities rather than individuals for results. 



The following detailed description is the result of the work done by Dr. R. 

 Pearl, of the Maine Experiment Station, in conjunction with his poultry staff. 

 The above station had used many different types of brooders, but each had its 

 objectionable features. Therefore, before the brooder which is described below 

 was known to any one outside of the station staff, it was experimented with under 

 all difficulties, in order to improve any mediocrity which might exist. 



It is from the above results that the writer feels thoroughly justified in 

 recommending the brooder to the poultrymen of this Province. Practical experience 

 has been exactly as outlined in the following lines, and the advantages are needed 

 by many who are engaged in the business. To point out the benefits derived there- 

 from, the main faults of the regular brooder are designated as follows : - 



Firstly : The mortality in the old type of brooder is found to be exceptionally 

 high within a few days after the chicks are placed therein. For example, if the 

 hover be situate in the centre, placed on a closed projection whereinto the heat 

 was conducted, invariably, on a cold night, the chicks would crowd in towards the 

 heated projection. The result was that one would pick from five to ten chicks out 

 each morning which had been trampled to death, until the number- was small 

 enough for all around the projection to get an even amount of heat. From this 

 point, we arrived at the conclusion that the heat was not evenly distributed, so, 

 therefore, one must first choose a hover which will throw out the heat to all parts 

 of the brooder.

Secondly: The difficulty in obtaining the required amount of heat could be 

 overcome only by having a higher flame. The flame being turned up, one would 

 get lottoin heat, which is not desired. Again, if a draught happens to strike a 

 too-high Hame, one would have a fire to contend with. 



Thirdly: One must also consider that the lamp-fumes and vitiated air must 

 be taken from the interior of the house, especially so when two brooders are oper- 

 ated in a small space. 



Fourthly : There is too much labour involved in the moving-about of the 

 small brooders of the box type. They are not only heavy and clumsy, but have to
