TYPES OF MODERN HOUSING 155 



are placed in the rear wall of each room, under the 

 nesting platform. This gives free sweep for air across 

 the pen below the hens, at night. At zero temperatures, 

 even White Leghorn combs do not freeze in this house, 

 the front being constantly open. A year's use has 

 proved the house satisfactory. Being built by contract, 

 of locust, poplar, and hemlock, with yellow pine for 

 roof sheathing and flooring, it cost ;^450, and gives com- 

 fortable quarters to 400 Leghorns. This is about ^1.12 

 per hen. The main floor gives nearly four square feet 

 per hen, and the birds have, in addition, the equal floor 

 space below. Poultrymen, as a rule, abominate an ar- 

 rangement like this, which has not head room for an 

 attendant, but it gives extra space without much extra 

 cost.
