The objective of this project was to gain an understanding of the factors causing lighter shell colour. The project aimed to produce a comprehensive literature review on eggshell colour and, through a series of experiments, to determine the location and nature of pigment in eggshells (shell and cuticle), and the location and nature of pigment synthesis in the oviduct. The project also aimed to identify ways of maintaining shell colour in older flocks and in alternative production systems.
