PROGRESSIVE POULTRY RAISING 



It is further the best natural disinfectant that we have 

 and is a great preventive of disease. A common fault 

 of farm hen houses is that they are too dark. 



The chicken house may be dry, well ventilated without 

 drafts and have window space sufficient to admit plenty 

 of sunlight and still give bad results if too many individuals 

 are crowded into a given house. For the older birds the 

 best results will usually be secured if from 3^ to 4 square 

 feet of floor space per bird is allowed. 



As a usual thing, the net returns from a flock of 100 

 laying hens kept in a house 20x20 will be greater 

 than from 200 hens kept in the same house taken 

 year in and year out. In years when the windows are 

 open and the birds can be out of doors most of the time, 

 the results from the crowded house might not be so bad,
