be carried from the house on the range to the storehouse, thus entailing too much 

 time in the busy season. 



With the brooder outlined the above faults are overcome. It I* so constructed 

 that it may be dismantled in five minutes, the hover and its parts put in one place. 

 and the different frames, etc., placed in under the floor of the brooder. Any plan 

 which is shown to be of a labour-saving nature should be welcomed by every poultry- 

 man in the Province. The advantages which we found to accrue from the use of 

 this brooder are as follows: 



It was found possible to rear a larger number of chicks in proportion to the 

 number originally put in than in any other brooder, and the mortality was much 

 lower. Furthermore, the chicks not only lived and grew quicker, but were more 

 thrifty than those raised in any other type. 



We must not let the problem of tuberculosis pass unnoticed. Although we do 

 not see it in so much young stock, the main way to help prevent this disease is by 

 allowing more fresh air to the young chicks from the time they leave the shell until 

 they are put into the laying-house. 



The Construction of the Brooder. 



With the idea in mind of obtaining a fresh-air brooder, it was deemed advis- 

 able to use a wall which is permeable to air. In meeting this requirement, the 

 outer side and front walls, as also the top \>t the brooder, were made of cloth. 

 Collectively speaking, the brooder is a cloth box containing a hover of the type in 

 which the lamp-fumes are conducted outside of the building by an exhaust-pipe. 

 These brooders may be built permanently into the house which they occupy. If 

 the house be 6 x 6 feet, we would not place more than one brooder in the same. 

 If it be 12 x G feet (as shown in Cut 1 i. two brooders may be run to their full 

 capacity. When two brooders are placed in the buildii:g. a part of the end wall 

 and part of the back wall of the building form two of the sides of each brooder. 

 The remaining side, front, and cover are made of cloth tacked firmly on light wooden 

 frames, as are shown in <'ut 2. The floor of the brooder stands 10 inches above 

 the floor of the house. From the front of the brooder a sloping walk extends down 

 to the floor of the house, reaching in width clear across the whole front of the 

 brooder. A small piece of burlap may be tacked on this runway to allow the 

 chicks to run up and down from the hover more easily. The cloth front and side 

 of the brooder are not permanently fixed in position, but are removable panels, 

 which are held together to the framework by hooks and eyes, cleats also being 

 placed on the floor and sides, as shown in Cut 3. The cover is hinged in the middle 

 in such a way that it can be either half or entirely open, and folded back out of 

 the way. The advantage of having it jointed in the middle is that the degree of 

 heat may be fixed more regularly, and that by folding over it is possible to turn up 

 against the back and roof, thus leaving no small holes for the chicks to fly into and 

 get lost, as shown in Cut 6. 



A hover of the circular type must be used in this kind of brooder. The lamp 

 is placed inside the house, underneath the brooder, on the floor. Two little 

 of wood should be nailed securely on the floor, to prevent the lamp from sliding 

 about. By having the lamp inside the house, we do not have any trouble from 

 winds or rains when we wish to light it. In the old type of brooder it often 

 requires a box of matches to light the lamp in the outdoor box. Heavy insulation 

 is also required on the inner side of the top of the hover or drum, to reduce the 

 of heat by radiation in the early spring. Detailed working drawings are given, as 

 seen in the cuts. Fig. 2 shows the end elevation of the brooder. Fig. 3 shows a 

 section through the middle of the brooder. Fig. 4 shows the floor-plan and arrange- 

 ment of the hover. Fig. 5 shows the brooder in operation. Fig. shows its appear- 

 ance when dismantled, with the parts stored in the base, yft the house is in use by 

 the larger chickens.
