THE VETERINARY SCIENCE 
Symptoms. — Small 
chickens are very frequently 
attadrked when exposed to 
favorable conditions, as we 
have outlined. The patient 
is "dumpish," sits about in 
the run and gapes frequent- 
ly. This is a sort of strain- 
ing, the head is raised, the 
eyes partially or wholly clos- 
ed, and the mouth thrown 
wide open in a sort of yawn. 
This action is frequently ac- 
companied by a sneeze or 
cough. There is soon loss 
of flesh and death. 
Treatment. — Prompt 
and stringent measures are 
necessary. Endeavor to re- 
move the cause at once and Fig. 104. Chicks Suffering from the Effect 
isolate every bird affected or °^ ^^p^ w^'^"'- 
showing the least signs of the disease. 
Sprinkle lime all over the floors and over the ground of 
the runs. This kills any of the worms and destroys the eggs 
that may be on the ground. It also kills all insects that 
may be a medium of carrying them. Boil out and disinfect 
all the feed dishes and water pans ; in fact, make a genuine 
and general clean up. If possible change the run altogether 
to other grounds. We cannot impress these precautions too 
strongly, as it is absolutely necessary that they be taken 
not only to cure the disease, but to prevent its recurrence. 
If the infected chickens are very bad and not very 
valuable, it may be better to kill them and burn the bodies 
and see that none of the discharge is allowed to remain about 
without being covered with lime. 
The windpipe may be swabbed out if very carefully 
performed. Put a couple of drops of carbolic acid in a pint 
of lukewarm water and use a feather with a stiff stem, but 
very soft, fluffy end. Open the mouth wide, dip the feather 
into the water, shake it, and carefully insert it into the wind- 
pipe, the opening of which may be easily seen. Turn the 
feather easily by rolling the stem slightly between the fin-
