temperature under the heater drum, a moderate living room temperature 

 between the drum area and the outside edge of the hover and a cool house 

 temperature outside the hover where the chickens have an abundance of 

 room to exercise in the cool air. During favorable weather a fourth 

 area of temperature is provided out of doors by a cloth fence enclosure 

 where the chickens can get to the ground early in a sheltered, sunny 

 spot. Fig. 69. 



4. A large extent of room for exercise. 



The chick is naturally active. It cannot continue in health under 

 close confinement. A young, active animal kept under restraint fails to 

 develop naturally. Opportunity to scratch and run is essential even from 

 the very first. The larger the floor space is per chick, the easier it is to 

 keep the brooder clean. The system here described provides 64 sq. ft. 

 floor space which is .32 sq. ft. floor space per chick where 200 chicks are 



kept in a house 

 In many of the 

 modern outdoor 

 brooders, there 

 is about 20 sq. 

 ft. floor space 

 equal to .2 sq. ft. 

 floor space per 

 chick with 100 

 chicks or .4 sq. 

 ft. floor space 

 with 50 chicks 

 in a brooder. 

 The larger 

 brooder gives 

 greater liberty 

 of action to 

 chickens than 

 does a smaller

same number of square inches floor space per chicken. 



5. An abundance of sunlight in a brooder is essential. 



Sunlight gives good cheer, adds warmth, kills the germs of disease, 

 keeps the litter dry and provides light for the chicks to hunt for food 

 in the litter early in the morning and late in the afternoon, all of which 

 are of great importance. 



The various plans for fronts here presented, provide for a liberal 

 supply of sunlight. Just where it is best to place windows and how large
