Several chicken breeds lay blue eggs, but the classic, most-cited ones are Araucana, Ameraucana, Cream Legbar, and various “Easter Egger”–type mixes.

Quick Scoop: What chicken lays blue eggs?

If you’ve ever cracked open a pale sky-blue egg and wondered who laid this? , you’re probably looking at the work of a hen with Araucana genetics somewhere in her family tree.

Main blue-egg breeds

  • Araucana – Often called the “original” blue-egg layer, originating from Chile, famous for being rumpless (no tail) and sometimes having little feather tufts by the ears.
  • Ameraucana – Developed later in the U.S. from Araucana lines; these birds have a beard and muffs on their face and lay lovely light to medium blue eggs.
  • Cream Legbar – An autosexing British breed (you can sex chicks by color) that lays pastel blue eggs and is popular in modern backyard flocks.
  • Easter Egger – Not a true standardized breed, but a mixed-type chicken that can lay blue, green, or even pinkish-brown eggs depending on genetics.

A simple rule of thumb:

If a chicken lays a genuinely blue egg (blue all the way through the shell, not just tinted), there is almost always some Araucana (or derivative) blood in the background.

How the “blue” works

  • Brown-egg layers deposit brown pigment on top of a white shell.
  • Blue-egg layers have a shell that is blue all the way through, inside and out, due to a pigment called oocyanin linked to Araucana-type genetics.
  • That blue gene can be combined with brown-layer genetics to create green and olive eggs in designer crosses like Olive Eggers.

Forum-style angle & “latest” backyard trends

Over the last few years, backyard-keeper forums and blogs have leaned hard into colorful egg baskets as a trend, with blue eggs nearly always credited to Araucana-derived lines like Ameraucana, Cream Legbar, and newer hybrids such as Prairie Bluebell and Whiting True Blue. Since around 2024–2026, articles and posts continue to highlight these breeds as “must haves” for people wanting Instagram-worthy cartons and farmers’ market displays.

You’ll also see more boutique hybrids (Super Blue/Bountiful Blue, Lakeside Egger, Sapphire Jewel, etc.) advertised by hatcheries specifically for reliable blue eggs and good production, which reflects how the blue-egg trend has gone from a niche curiosity to a mainstream backyard goal.

TL;DR

  • The most famous chickens that lay blue eggs are Araucana , Ameraucana , Cream Legbar , and various Easter Egger–type crosses.
  • Many modern hybrids (Prairie Bluebell, Whiting True Blue, etc.) also lay blue eggs and are bred to keep that color consistent while boosting egg numbers.
