Duration of Annual Molt 



in. 

 Relation to Egg Production 



By F. A. Hays and Ruby Sanborn 



It is generally recognized that there is a very direct relationship between 

 egg production and the annual molt of hens. The time and duration of 

 the molt period is therefore of economic significance to the poultry raiser. 

 This investigation was undertaken in an attempt to more definitely deter- 

 mine the factors entering in this relationship.
