 soiling of the bird's feathers. 



Diarrhea may result simply from an upsetting of the 

 digestive organs due to improper feeding or it may be a 

 symptom of some more serious disease. Simple diarrhea 

 may arise from the presence of indigestible matter in the 

 alimentary canal, it may be due to exposure to heavy rains 

 or to drafts in the roosting house. In the latter cases a

 tary canal. 



Treatment. — Simple diarrhea will usually require no 

 treatment other than removing the original cause. This 

 latter is by far the more important thing to be done. If 

 neglected, the condition may become chronic and may result 

 in more serious disturbances of the alimentary system. It 

 is often beneficial to replace part of the bran in the mash 

 with middlings or low grade flour. Where in addition medi- 

 cal treatment seems desirable the first thing to do is to 

 remove the fermenting material from the intestinal canal. 

 This can be done with Epsom salts, using a small half tea- 

 spoonful to each bird. This should be dissolved in water 

 and used to mix the mash. If more convenient, a teaspoon-
