the chicks and severe losses are therefore sustained 

 from overcrowding. Several good brooders are here 

 described. 



The Up-to-Date Brooder — A good homemade 

 brooder that is up to date and can be depended on to 

 raise a good percentage of the chicks intrusted to it 

 when rightly managed is illustrated in Figure 85, 

 and was described in Farm Poultry by Dr. Woods. 

 It has stood the test of several seasons under varying 

 conditions, and has successfully reared ninety per cent 

 of the chicks placed in it. It is an economical brooder 

 to build, and the cost for material, where all new stuff 

 is used, need not exceed $5 (this including lamp). 

 By utilizing waste stock it can be made for less than 

 $3 (labor not included). 



The brooder is made three feet wide from front to 

 back, and three and one-half feet long from side to 

 side. A general perspective view of the brooder com- 

 plete is shown in Figure 85 with the smaller section of 

 the movable roof removed and the loose board used for 

 lamp door partly open. The front view shows how the 

 windows are arranged and the door, Wj by which the 

 chicks enter and leave the brooder; an opening is left 

 for inlet of fresh air into hot air chamber; there are 

 two of these openings, one opposite the other. These 

 openings may be made in the sides if more convenient. 

 They are one and one-half inches wide, and the depth 

 of the board which separates the iron floor of the; 

 hot air chamber from the floor of the brooding cham- 

 ber. In cold weather it will prove economy in oil and 

 heat to partially close one of these openings. The 

 sectional view shows the construction of the brooder in 

 detail. 



The lower frame for the lamp chamber is built 

 first, and is made of sufficient hight to accommodate 

 your lamp, and leave a space of nearly an inch between
