24 OPEN-AIR POULTRY HOUSES 



to 40 degrees below zero in winter, said : "Woods' open-air colony 

 poultry houses. We want fresh air night and day to insure health. 

 This is a eold country in winter,'' 



Bulletin No. 183, Maryland Agricultural Experiment Station, 

 says : 



"A few years ago the open-front poultry house was practically 

 unknown. The tendency at that time was to construct houses that 

 were very tight, and ventilated by the opening of windows, and in 

 many instances by means of flues and cupolas. This type of house 

 as a rule was more or less damp, and it did not take many years for 

 progressive men to realize that damp houses meant cold houses and 

 an abundance of disease. The result has been a gradual increase 

 of the amount of fresh air in the house, and less attention given 

 to warmth, until today we have what is known as the open or cloth 

 front house. One can still find, however, many types of poultry 

 houses, but the open-front house is fast becoming the standard for 

 every climate. 



"The beneficial effects of a dry house with an abundance of 

 fresh air, has been very forcibly demonstrated by several Experi- 

 ment Stations. * * * The open-front house can be modified to 

 meet a wide range of climate. * * * 



"In different parts of the state where new buildings are being 

 erected, the open-front or fresh-air idea was in evidence. There is 

 little doulit but that the open- front house is one big step toward 

 putting the poultry industry on a firmer basis, and for houses of 

 all sizes this type of house is strongly recommended." 



Manager A. Carr, of the Milton Poultry Station, New Zealand, 

 recommends the open-air system of housing and says : 



"Owing to the continued increasing demand for breeding stock 

 and sittings of eggs, I have been obliged to further increase the 

 accommodation by altering a number of the original houses and 

 adding the new type of cheap 'open-air houses.' These have proved 

 a complete success in every way and prove beyond all question that 

 the old style close and expensive house is quite unnecessary for the 

 keeping of poultry for profit." 



In the 1909 report of the Poultrv Division of the Now Zealand 

 Department of Agriculture is the following : 



"Experiments carried out at the Milton Station in the open-air 

 system of housing have proved very satisfactory, and the system 

 can now be recommended to poultry raisers in any part of the 

 Dominion, no matter how severe the climate." 



A successful user of open-front poultry houses refers to the old- 

 fasluoned type of closed house as a "roup factory."
