SANITATION 



Regardless of the type of construction of the laying house, if the 

 birds are to be kept free from disease and in a vigorous condition, it 

 is necessary to practice careful and thorough sanitation. This work 

 naturally groups itself along three lines, namely: 



The droppings should be removed from the dropping boards when- 

 ever they are wet and give off objectionable odors. When by the use 

 of absorbents, the moisture can be kept from tliem they are not 

 harmful. It will usually be found most economical to do this clean- 

 ing at least twice a week during the winter.
