but cause so little discomfort in grown stock that 

 such cases are seldom noticed. In chickens, how- 

 ever, they cause sickness and death, so gapes is 

 known as a disease of chickens. 



Chicks with gape worms suffer great irritation in 

 the wind-pipe, while they sneeze, cough, and gape, 

 stretcliing the neck in an effort to relieve their 

 irritation. At this time they will often cough up 

 the worms and other birds will quickly swaUow 

 them, thus getting into the same trouble. 



Gape worms are present in yards not frequently 

 changed, and their eggs have been foiuid in earth 

 worms. Whether this proves that earth worms are 

 bad for chickens, as found in scratching about the 

 yard, is a question. With plenty of sharp grit in 

 its gizzard, the active chick could handle many 

 such worms, under clean conditions, and grind them 

 up, eggs and all, in jig time. The real danger is 

 sour soil, and unclean eating trays. 



Wire worm-extractors are supplied with full 

 directions for use by poultry houses. Take 

 afflicted chicks out of the flock, and place them in 

 coops, where all droppings can be collected and 

 burned.
