Sunlight is one of the most powerful ot disin- 

 fectants, even a parasiticide for certain young par- 

 asites, and is necessary to the health and con- 

 tentment of the fowls. It has the advantage also 

 of revealing filth in the building which might 

 otherwise escape the eye of the attendant, and re- 

 main to breed disease in the flock. 



Ventilation should be definitely provided for in 

 the construction by ventilators and the proper 

 arrangement of doors, windows and other open- 

 ings and not left to cracks in the walls and to 

 chance openings. Cracks in the walls are an abom- 

 ination and ever present protection to, and nursery 

 for external parasites, and a harbor in which 

 disease germs may weather the application of dis- 

 infectants. 



The interior of the poultry house should be 

 whitewashed after a thorough cleaning and disin- 

 fecting, twice, or better, four times a year. White- 

 wash is desirable because of its clean appearance, 

 its cheapness, and the ease of its application (use 

 a sprav pump), because of the antiseptic value 

 of the Ume, and because of its high reflection of 



The roosts should, of course, be removable to 

 permit of cleaning, and should come near to the 

 floor so that heavy birds may not be injured m 

 jumping off of them. Like the walls, they should 

 be free from cracks and whitewashed two to four 

 times yearly. During the hot season, the roosts 

 should be wet with kerosene once a week. This 

 will aid verv materially in keeping mites and lice 

 from the fowls. Dropping pans placed under the 

 roosts are a convenience worth while, for sanitary 

 reasons.
