Chick mass gains are affected by food delivery rates and parental body mass.

Abstract

<p><b>a.</b> Residual of chick mass on chick age increases with residual of adult mass on chick age. <b>b.</b> Lipid (filled symbols, filled line) and energy (unfilled symbols, dashed line) delivery rates increase with the residual of chick mass on chick age. Values shown are the residuals relative to the residuals for the same individual on the first day of the experiment.</p
