Commonly brown and white are the two major eggshell colors in chickens. Protoporphyrin-IX, biliverdin, and biliverdin zinc chelate are the primary pigments of the eggshell, and several blue egg-laying breeds have been reported worldwide.

The Araucana, an indigenous breed from Chile, was the first chicken breed described to lay blue eggs and has been frequently used in genetic studies of the blue eggshell phenotype. Blue eggshell color exhibits an autosomal dominant inheritance, and eggs laid by homozygotes are a darker blue than those from heterozygotes.

In 1933, Punnett first reported that the Araucana's blue or green shell appearance was determined by a single genetic factor, traditionally denoted as oocyan (O). In IQ Genetics, our test determines the following genotypes:

o/o (white/brown egg)
o/O (heterozygotes blue egg)
O/O (homozygotes BLUE egg).
