Winter Pause In Rhode Island Reds 



By F. A. Hays 



Many pullets stop laying for four or more successive days during the 

 winter months. These nonproductive periods cause considerable 

 economic loss which is becoming more serious as higher levels of egg 

 production are being attained. This report is part of an attempt to 

 develop methods for the control or elimination of winter pause.
