242 POULTRY CULTURE 



Spread. — Birds become infested by coming in contact with 

 other birds with scaly legs, or by being placed in shipping 

 coops or placed in buildings or runs in which birds with scaly 

 legs have been kept. 



No birds should be sold for breeding purposes from a flock 

 with scaly legs, nor should such birds be exhibited in the show- 

 room or shipped in crates breeding stock is to be shipped in. 



Treatment. — ^In treating a bu-d with scaly legs, first soak the 

 scabs with warm water, then with a nail-brush remove by 

 scrubbing all scabs possible to be removed. Scrape with a dull 

 knife, then after the legs have dried saturate them with kero- 

 sene. Kerosene penetrates deeper than watery solutions and 

 is a powerful parasiticide or parasite destroyer. Repeat this 

 treatment once every five days for several applications. A 

 hot solution of Hme and sulphur dip, as used in sheep dipping, 

 has been used with excellent results. 



Thorough eradication from an infested quarter is difficult. 

 The greatest number of parasites off the bird will probably be 

 found in the nests and on the roosts, and disinf estation of these 

 and other parts should be looked to as under lice.
