Attention should also be called to the fact that poultry 

 houses that are dark and damp fninish very favorable 

 places for the growth of these insects. Tlien, also, 

 fowls that are poor in condi- 

 tion are jnore apt to be in- 

 fested with lice than those 

 that are in goiod condition, 

 healthy and sturdy. It has 

 been noticed fre(iuently that 

 where there are a number of 

 fowls in an infested pen 

 tlnose that are least rugged 

 harbor tlie most lice. The 

 probable reason fcir tliis is 

 that fowls in poor condition 

 have a somcAvhat drv and

more hiding places and more food for lice than the 

 smooth, pliable skin of the perfectly healthy bird. 

 When fowls are afflicted in this way it can be noticed 

 that they are uneasy and restless, they are constantly 

 pecking at different parts of the body and scratching 

 and shaking themselves. They also have an inclina- 

 tion to dust themselves and when caught and ex- 

 amined the lice can frequently be seen, when tlie feath- 

 ers are spread apait. and especially about the head 

 and neck, where they cannot be reached by the bill of 

 the animal, beneath the wings and sometime* on all 

 parts of the body. They may also be found in many 

 cases, if a careful search is made, in the nests, on th<' 

 perches and in cracks and out-of-the-way places at any 

 point in the building. 



In attemjiting to destroy lice it is necessjiry not only 

 to treat the fowl but also the j)remises occu]iied by it.
