History of the Olive Egger chicken breed

The history of Olive Egger chickens is a tale of innovative crossbreeding and a quest for unique egg colors. The term "Olive Egger" refers to a hybrid chicken breed that is specifically bred to lay eggs in various shades of olive or moss green. While Olive Eggers are not recognized as a standardized breed by the American Poultry Association, they have gained significant popularity among backyard chicken keepers and breeders.

Olive Eggers originated in the early 20th century through crossbreeding of heritage chicken breeds. Breeders aimed to produce greenish-hued eggs by selectively breeding chickens with blue and dark brown egg-laying traits from breeds like Araucana, Ameraucana, and Marans.

Through careful and strategic mating, breeders were able to produce offspring that inherited genes for both blue and dark brown egg-laying. The resulting hens, known as Olive Eggers, would then lay eggs with various shades of olive green. It's important to note that not all Olive Eggers will lay the exact same shade of green, as the color can vary depending on the specific genetics inherited from their parent breeds.

Olive Eggers are typically not aggressive and get along well with other chickens. They generally integrate smoothly into a mixed flock, forming strong bonds with their flock mates. They are not typically at the top of the pecking order, but they can hold their own and establish their place within the hierarchy.

Overall, Olive Eggers make wonderful additions to a backyard flock due to their friendly and easygoing nature. Their engaging personalities and calm demeanor make them delightful companions, whether you're a seasoned chicken keeper or new to raising poultry.

I have seven chickens about 10 months old, one gave olive eggs for a month before the cold weather. Now she seems unhappy and is pecked at by the flock, she’s scared of them and not allowed to share food and water. Her comb is dull and pale. We have snow and approx 11-20*f temps so they stay in their coup/ shed 24/7 right now, can’t wait til they get outside. Any suggestions ?


Much like Elizabeth noted above- 1 of our Olive Eggers has a poofy little feather pompadour on top of her head. We call her Jamie Brown; I’m so curious to know which combination/breed this feature came from. Our other Olive doesn’t have this feathery updo.


Hi thanks for the info on Olive Eggers. It’s been a few years since I’ve had chickens. I have two of the four I bought from tractor supply this late spring. My young dog took out two unfortunately before I got my new coop built. We are working on this issue he seems to understand now they are family. I’m super happy with them. They have not laid an egg yet. I believe they’ll start soon. I would be interested to know if the rooter of this breed would have the same temperament. I’d love to have a rooster but all of my past experiences have been with mean roosters! Thanks

I have 2 hens and two roosters. My grandson brought home chicks they had at school. The first egg that was laid was a light olive green. The two hens both look like Brahmas, only one has puffy cheeks. Is the one with puffy cheeks the egger?


Okay im just gonna say upfront that I think i have an Olive Egger but dont have any labeled documentation to prove that! Because tue five month old hen in question was one of eleven chicks born here at home and not purchased elsewhere. I know the mother is an Welsummer and the Father is an Egger thats Plymouth Rock mix with Easter Egger. So that said i will note she looked like a hawk to me and my husband and before we knew she was a she we had called her Hawk! Anyhow now that she has recently began giving us beautiful greenish leaning more towards khaki colored eggs Im assuming she falls under your Olive Egger category?
