1. I'OULTKN' IlorSI-: IIVC.IKNK AND SANITATION. 



./. Cleanliness. — The thing of paramount importance in the 

 hygienic housing of poultry is clca)iiincss. ]W this is meant not 

 merely plain, ordinary cleaning up, in the housewife sense, but 

 also bacteriological cleaning up; that is, disinfcctioJi. All build- 

 ings or structures of whatever kind in which poultry are housed 

 during any part of their lives should be subjected to a most 

 thorough and searching cleaning and disinfection- a^ least once 

 every year. This cleaning up should naturally come for each 

 different structure (i. e., laying, colony or brooder house, indi- 

 vidual brooder, incubator, etc. ) at a time which just precedes 

 the putting of new stock into this structure. 



Hoi^' to clean a poultry house: Not every poultryman of 

 experience even, knows how really to clean up a poultry house. 

 The first thing to do is to remove all the litter and loose dirt 

 which can be shovelled out. Then give the house — floor, walls 

 and ceiling — a thorough sweeping and shovel out the accumu- 

 lated debris. Then play a garden hose, with the maximum water 

 pressure which can be obtained, upon floor, roosting boards, 

 walls and ceiling:, until all the dirt which washes down easilv is 

 di.sposed of. Then take a heavy hoe or roost board scraper and 

 proceed to scrape the floor and roosting boards, clean of the 

 trampled, and caked dressing and dirt. Then shovel <nit what 

 has been accumulated and get the hose into action once more and 

 wash the whole place down again thoroughly and follow this 

 with another scraping. With a stiff bristled broom thoroughly 

 scrub walls, floors, nest boxes, roost boards, etc. Then after 

 another rinsing down and cleaning out of accumulated dirt, let 

 the house dry out for a day or two. Then make a searching 

 in.spection to .see if any dirt can be discovered. If so apply the 

 appropriate treatment as outlined above. If. however, every- 

 thing ap/^ears to be clean, the time has come to make it really 

 clean by disinfection. To do this it is necessary to spray or 

 thoroughly wash with a scrub brush wet in the solution used all 

 parts of the house with a good disinfectant at least twice, allow- 

 ing time between for it to dry. For this purpose 3 per cent
