DISEASES AND PESTS OF FOWLS 



the skin becomes puffed out in one or more 

 places, generally on the neck. In rare cases 

 the puffing spreads over nearly the whole 

 of the body. 



Cause. This disease is evidently caused 

 by some obstruction of the air passages that 

 forces the air to escape under the skin. 



Treatment. Let out the air by punctur- 

 ing the skin. Give soft and nourishing 

 food. It will probably be wiser not to use 

 birds that recover from this complaint for 

 breeding stock. 



EPILEPSY 



An unusual complaint 



Symptoms. The bird staggers about and 

 has a fit. It may recover. 



Cause. It is difficult to discover a cause ; 

 intestinal worms are suspected in some 

 cases. 



Treatment. If it is suspected that intes- 

 tinal worms are responsible, try the treat- 

 ment recommended for worms. (See 

 page 95.)
