Age and body weight at sexual maturity in female white Leghorn chickens.
Age and body weight at sexual maturity were measured in females from two lines of White Leghorns known to differ in these traits. Within-line correlations between age and body weight at sexual maturity were not different from zero. The data demonstrated that egg-type chickens must reach a minimum age and body weight before commencing egg production - results consistent with those obtained for meat-type chickens and Japanese quail.
