Figure 1. — Individual Hatching Record 



There should be one small sheet for each female. The record includes date set, date on which 

 each egg was laid, number infertile, number dying early, number dying late, and number of chicks 

 hatched. At the close of the hatching season these data may be summarized for each female.
