of carrying back and forth parts from a storage house each 

 year is avoided. To bring about this result the size of the 

 base is so calculated that all the parts of the brooder may be 

 enclosed in it. The way in which this is done is apparent from 

 an examination of fig. 3. It will be seen that the end of the 

 brooder base, (marked A A in the diagram) is removable, being 

 held in place by buttons bb. When the end of the brooding sea- 

 son is reached and there is no further use for the brooder that 

 year, the side and front end panel of the brooder are removed, 

 the canvas cover folded back and tacked to the wall of the 

 building and the hover dismantled. All of the parts are then 

 shoved under the brooder floor and the panel AA put back in 

 place again. The floor of the brooder is removable so that it, 

 and the floor underneath, may be cleaned and disinfected. 

 By removing its legs the hover may be stored in the brooder 

 base along with the other parts, or if one does not desire to 

 do this the hover may be suspended close up to the roof 

 of the building. In that position it will be impossible for the 

 birds to roost on it. Of course, all movable parts should be 

 taken from the hover before it is hung up in this way. These 

 parts may be stored in the brooder base. After the chickens 

 are out of the house in the fall the parts of the brooder are 

 taken out, thoroughly cleaned and disinfected, and then the 

 whole is reassembled and made ready for the hatching season of 

 the next year. 



Detailed working drawings of the brooder are given here- 

 with. Fig. 3 shows the end elevation of the brooder ; fig. 4 

 shows a section through the middle of the brooder ; fig. 5 shows 

 a floor plan; fig. 6 shows the brooder in operation; and fig. 7 

 shows its appearance when dismantled and with the parts stored 

 in the base, while the large chickens are using the house. All 

 dimensions are given on these drawings and from them it 

 should be possible for anyone to construct the brooder for him- 

 self. 



As material any sort of planed lumber may be used. Prob- 

 ably pine will be found satisfactory and economical in most 

 cases. Spruce or hemlock may be used to build the base, if 

 one desires. For the cover and removable sides almost any 

 sort of cloth may be used. Here we have employed the lightest
