What type of chicken do blue eggs come from?

They are a breed originating from Chile, known for their distinctive blue eggs. They are not the only breed to lay blue eggs, though, as some other breeds like the Ameraucana and Easter Egger also lay blue or green eggs.

The color of the eggs is determined by a gene that affects the pigment in the eggshell. The Araucana breed has a gene that produces a blue pigment, resulting in the distinctive blue eggs.
