6o The Essentials of Poultry Raising 



strong hard rubber syringe will drive the material clear through 

 the nasal passage and out into the mouth through the slit in 

 the upper part of the mouth. If the bird's head is held down, 

 this material will run out of the mouth and not infect the wind- 

 pipe (trachea) and thus cause complications. Always wash the 

 hands in a 4 per cent solution of some standardized coal tar 

 disinfectant dip before handling other birds. 



129. How to Prevent Spread of Roup. Thoroughly clean the 

 yard and house. Spray the house thoroughly with a 4 per cent 

 solution of some standardized coal tar disinfectant dip. Such 

 a dip can be secured at any drug store and should have a 

 coefticiency of at least 5 per cent. Put permanganate of potash 

 in the drinking water. Get a fruit jar and fill it with water. 

 Place in this water crystals of permanganate of potash until 

 some of it is left in the bottom undissolved. When the drink- 

 ing water is prepared for the flock, pour in enough of this stock 

 solution of permanganate of potash to make the water slightly 

 purple. Always promptly remove all birds with roup from the 

 rest of the flock and look out for the chronic carrier. 



130. Swollen Eyes. Usually but a single eye is found to be 

 swollen at a time. The germs of roup are responsible for one 

 kind of swollen eyes. In this kind, the lining of the eye will 

 be noticed to be red or inflamed. There will be an accumula- 

 tion of a white, clot-like matter. \Mien the bird sleeps at night, 

 a small amount of this material dries along the outer edge of 

 the eyeball, with the result that the bird cannot open its eye 

 in the morning. The material continues to accumulate and the 

 eye becomes enormously swollen. 



131. How to Treat Swollen Eyes. Gently press open the eye- 

 lids with the thumb and finger. Remove with a small pledget 

 of cotton this white, clot-like mass and inject a small quantity 

 of soda solution, as in the case of roup (128). Then inject a 

 small quantity of the oil, as in roup. Repeat this treatment 

 twice a day. A 10 per cent solution of argyrol or a 1 per cent 

 solution of zinc sulphate may be used.
