Liver Disease 



Caused by lack of exercise, overfeeding, or feeding 

 too rich foods. 



Sanborn mentions as early symptoms: "Rough 

 plumage, watery diarrhea, first brownish then yel-

 indigestion. 



TREATMENT. If the crop-bound condition is 

 caused by swelled grain, the bird may often be 

 treated without an operation. First give the bird a 

 teaspoon of castor oil. After allowing this a little 

 time to work into the crop begin to knead the hard
