3. Canker or Ulcerated Mouth. 
Causes. — Canker is caused by filthy quarters and musty 
or unwholesome food. 
Symptoms. — It makes its appearance as running sores 
on the head, in the 
mouth or throat accom-

salt and wash the head 
and eyes, also swab out 
the throat and mouth. 
Remove ulcers with a 
quill and apply powdered 
borax to the places left

4. Crop Bound. 
This is impaction of 
the food in the crop. 
Causes. — Eating indigestible food or some foreign sub- 
stance — bone, dry grass — that may obstruct the passage or 
eating a very large quantity of grain may cause it. 
Symptoms. — The mass of food may be felt easily. 
Treatment. — The best treatment for crop bound is castor 
oil. Give the fowl two teaspoonfuls in one dose. If this 
does not clear it in 48 hours it may be necessary to open the 
crop and remove the contents. 
Carefully remove the feathers from a greater portion of 
the crop and chill the skin with a piece of ice or ice-cold 
water. Make an incision in the skin from two to three 
inches in length, according to the size of the bird, near the 
top. Draw the skin back and make another opening in the 
crop so that the two openings do not come opposite each 
other, as this helps healing after the operation. Remove
