170 PRACTICAL POULTRY PRODUCTION 



stages of this disease should be removed, killed and burned. 

 Ten grains of potassium permanganate or as much as will 

 remain on the surface of a dime should be added to each 

 gallon of drinking water and kept before the chicks until 

 they are at least 4 weeks old. 



Intestinal worms. Many chickens are infected with one 

 or more kinds of intestinal worms. It is only, however, when 

 the growing conditions are not favorable, as when the brood- 

 ers or growing houses are very crowded, that this trouble 

 manifests itself. The worms so infecting chickens are us-

Symptoms. When worms are present, the bird becomes 

 thin and listless, the comb loses its color, turning purple, 

 and the eyes have a staring look. In general, the bird appears 

 unhealthy. Often intestinal worms prove their presence by 

 being found in the droppings. 



Prevention. As a general prevention transfer the birds 

 to a range to which fowls have not had access previously. 

 The old range should be well plowed and sown in some crop 

 before allowing the birds to return. 



Treatment. The following remedy has proven effective 

 in treating chickens for this trouble. On the basis of 100 

 birds to be treated, soak 1 pound of finely chopped tobacco 

 stems in water for 2 hours. Mix this Uquid with half of 

 the usual amount of mash feed that is usually fed for the 

 day. All feed should be withheld from the fowls so treated 

 for 24 hours previous to the treatment. Two or three 

 hours after feeding this mash mix one fourth of the usual 

 dry mash that is fed during the day with water in which 

 11 ozs. of epsom salts has been dissolved. It should be 

 remembered that this treatment and the amounts given 

 are on the basis of 100 birds. This treatment, as described, 

 should be repeated 10 days later. 



Gapes. This trouble is due to the presence of small
