A New Objective Measurement of Eggshell Color.: 1. A Test for Potential Usefulness of Two Color Measuring Devices

Abstract A new technique for obtaining objective measurements of eggshell color was explored using the Hunter Lab Colorimeter D25A-9 and the Minolta Chroma Meter CR-200. A total of 1,299 eggs from 161 hens in five lines were measured on these two color meters. Measurements for individual eggs were highly repeatable (P>.25); differences between hens were significant (P
