44 OPEN-AIR POULTRY HOUSES 



can be housed and yarded on from two and one-half to four acres, 

 according to the lay of the land and the shape of the lot. For 

 laj'crs smaller yards may be used or the birds may be confined to 

 the houses and not allowed to run out. Some successful egg pro- 

 ducers use the latter method, keep the layers confined to the house, 

 push them hard for egg production, market the flocks when egg 

 yield falls of! in summer, just before moulting time, and then stock 

 the houses up again with new flocks of pullets and young hens.
