FIG. 144 OVARY AND OVIDUCT OF GOOD AND POOR-LAYING HENS 



CONTRASTED 



This remarkable illustration shows, on the reader's left, the ovary and oviduct of 

 heavy-laying Rhode Island Red hen, and on the right the egg organs from poor-laying 

 hen. Both hens were actively laying, but the poor producer's ovary shows a much 

 lower state of activity shorter cycles with long periods between and this is con- 

 firmed by the noticeable smaller size of the oviduct which suggests also that the hen 

 has not been laying for so long a period as the one on the left. Photo from Conn.
