Chickens That Lay Blue Eggs

Blue is the one eggshell colour that goes all the way through the shell rather than being painted on the surface, and it comes from a single dominant gene carried by a short list of breeds. Everything else marketed as "blue" is really a green or olive egg — a blue-gene bird crossed onto a brown layer — which is a fine egg but a different thing.

These 11 breeds lay a true blue egg. Ameraucana, Araucana and Cream Legbar are the ones you can readily buy; the Whiting lines and Prairie Bluebell Egger round out the common list. If you want the deep teal of an "Easter egger" basket, pair one of these with the green and olive layers on the sister page — the mix is what fills a carton with colour.

These match too, but few or no US hatcheries stock them — expect a breeder waitlist.
