The Flock

Chickens That Lay Green and Olive Eggs

A vintage-style rooster print from Story Thyme Farms

Green and olive eggs are the arithmetic of eggshell colour: a blue shell with brown pigment brushed over it. The bird has to inherit the blue gene from one parent and a brown-laying line from the other, which is why "olive egger" describes a cross rather than a stable heritage breed. The darker the brown parent, the deeper the olive.

These 6 breeds and lines lay green to olive. Olive Egger and Whiting True Green are the reliable picks; a true Easter-egger basket comes from keeping several colour genes in one flock. For the darkest olive, cross a Marans (see the dark-brown page) onto an Ameraucana yourself — the result is the deepest egg most flocks will ever produce.

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