Roup 



Roup occurs in many forms. It may affect the 

 head, the eyes or the throat, but there is in all cases 

 great depression and dullness, with a putrid odor 

 which is characteristic of the disease. Where there 

 are symptoms of a cold with a noticeable odor al- 

 ways look for roup. There is usually a discharge 

 from nostrils or eyes, often the eyelids are stuck to- 

 gether or swollen shut, and in many cases there are 

 abscesses under the eyes or about the head.

 breeds, are much predisposed. 



"In the first stages of roup the birds often cough 

 or sneeze, and the breathing is noisy, caused by the 

 partial closing of the air passages which become 

 blocked with the discharge from the nostrils. When 

 the air passages are entirely closed, the fowl has to 

 open its beak in order to breathe. 



"Sometimes a yellowish cheese-like mass forms in 

 the nostrils, growing quickly and pressing the upper 

 walls of the nose upwards ; if this mass is removed, 

 an uneven bleeding surface is left which forms a new 

 cheesy mass in from 24 to 48 hours. 



"In more serious cases the face of the roupy bird is 

 swollen, especially between the eyes and nostrils, 

 and this swelling, which is hot and sore, sometimes 

 grows into a tumor as large as a walnut. Sometimes 

 the tumor grows inside the nostril and forces the 

 roof of the mouth downward."
