A Study on the Relationship Between Eggshell Color and Eggshell Quality in Commercial Broiler Breeders [PDF]
International Journal of Poultry Science, 2008 In this experiment, two trials were conducted to determine whether broiler breeder eggshell color could be used as an easy means of predicted eggshell quality. In Trial 1, 4320 commercial broiler breeder eggs were obtained. Specific gravity (SG) was measured and color determined on the eggs on the day of lay.

Avian eggshell coloration predicts shell-matrix protoporphyrin content [PDF]
Canadian Journal of Zoology, 2022 Avian eggshell pigmentation may provide information about a female’s physiological condition, in particular her state of oxidative balance. Previously we found that female House Wrens (Troglodytes aedon Vieillot, 1809) with lighter, less-maculated, and redder ground-colored shells were older and produced heavier offspring than females laying more ...
