COMMERCIAL EGG FARMING 9 



T. The housing unit, suitable for 400 birds, 

 is 180 feet long and nine feet wide, which 

 allows a trifle over four square feet of floor 

 space per bird. It faces the south and is 

 surrounded by an acre of land. The south 

 half acre is used in winter and the north half 

 acre in summer. Each yard as it is vacated 

 is plowed and harrowed and sowed with thou- 

 sand-headed kale. All houses are regularly 

 cleaned and disinfected.
