CHAPTER XIII. 
DISEASES OF THE HEAD, THROAT AND LUNGS. 
1. Common Cold. 
Causes. — What may cause a cold in any other animal 
may produce the same effect in fowl — exposure to cold, damp 
quarters, cold rain and drafts — especially if the vitality is 
low and the physical condition not as it should be. 
Symptoms. — There is a discharge from the nose and 
sneezing, as if to get rid of it. The nose may become 
plugged to such an extent as to cause breathing through the 
mouth. There is also a swelling of and running of water 
from the eyes. 
Treatment. — Remove the cause. See that the hen house 
is dry and warm and drafts are prevented. Provide for good 
ventilation and plenty of sunlight. 
Feed warm food. A spoonful of ginger or a little com- 
mon black pepper added to the mash is a good thing. Wash 
out the mouth with a little warm water and salt and bathe 
the nostrils if badly clogged up. Apply a little of the eye 
wash to the eyes and head. 
2. Roup. 
Roup is considered by all poultry men the worst and 
most dreaded disease than can afflict poultry. 
Causes. — Roup may be the result of a neglected cold. 
Unclean, damp^ poorly ventilated quarters, accompanied by 
poor feeding, are conditions ideal for the development of 
roup. Just so far as these conditions exist, just so great is 
the liability of becoming affected. 
Symptoms. — The first noticeable symptom is a dis- 
charge from the nostrils accompanied by sneezing, being 
merely the appearance of an ordinary cold. As the disease 
progresses the discharge is more profuse and thick, fre- 
quently drying about the mouth and nose. The eyes soon 
become inflamed, the birds stand about with the feathers
