 to over one hundred feet long where large numbers are kept in one 

 flock. The last is the most economical unit where eggs are of 

 primary consideration (Fig. 68). 



Simplicity of Design. — In planning and building poultry houses 

 it should be the idea to have the design and construction as simple 

 as possible. All extra trimming and ornamental features add 

 greatly to the cost and do not enhance the efficiency. Quality in 

 construction should also be considered, to make all permanent 

 buildings as durable as possible. Movable structures of small

 interior of the house damp and cold in the winter. Roup has been 

 very prevalent where the walls were of concrete. Concrete-block
