ARTIFICIAL INCUBATING AND BROODING

boards which bridge the opening. By moving these boards, 

 which are loose, ventilation may be obtained at the back, 

 front or middle of the hover, and the cleaning of the brood- 

 ers is greatly facilitated. This is quite a saving on a large 

 plant. 



In the short end of the house chaff or sand is placed in the 



brooders to the depth of 5 or 6 inches, so that the smallest birds 

 are brought near the pipes and as they grow the amount of 

 litter is decreased, thus giving them more room and taking them 

 further from the heat.
