Blue and Black Australorp Chicken: A Prolific Egg Layer

An Australorp Hen Once Laid 364 Eggs in 365 Days


Breed: Australorp Chickens

Origin: Originating in Australia, the Australorp chicken breed arrived in the 1920s in America and other parts of the world. They originated from Black Orpington chickens in Britain, which were imported to Australia, where they were mated with Langshan blood to raise their status as meat and egg birds. Since then, this heritage chicken breed’s numbers have dwindled. It was briefly placed on the Livestock Conservancy’s threatened list, and is currently labeled as a recovering breed. They are prolific brown egg layers, and even hold the world record, as one hen laid 364 eggs in 365 days, according to the Guinness Book of World Records.

Standard Description: Australorp chickens get their name from their origin as “Australian Orpingtons,” which had been called “Utility Type Orpingtons” before that. They were essentially early Black Orpingtons, and were imported into Australia around the late 1880s. They were refined for Utility purposes and later after the Orpington had been modified in Britain, exported back as Australorps in the early 1920s. They were admitted to The Standard of Perfection in 1929.

Comb: Five distinct points, upright, and ranging from deep pink to red.

Quote from an Australorp chicken owner: “My Black Australorps came from Mt. Healthy Hatchery. They have been healthy, active and friendly birds from the beginning. They are a great bird to have around kids and family. Black Australorps are beautiful additions to a backyard flock. There is nothing prettier than watching their black feathers become iridescent in the sun reflecting stunning blues and greens. These are prolific egg layers and do well in hot and cold weather. I love that Black Australorps have black legs and feet with white toenails. It almost looks like they’ve had a manicure!” – Pam Freeman of

    I have australorp crosses and they are nice to have around. They don’t lay every day but that is ok with me.

  • My Australorps aren’t laying yet….They are 9 months and haven’t layed an egg yet !! But they are beautiful !

  • I have a beautiful Astralorp that has laid a hugh brown egg every day. She is the only one laying consistently since the onset of winter. She refuses to use the nesting box and I think she is laying while she roosts at night. I have a liner under their nesting rod that hangs from one pole to another and I find her egg in it quite often, making me think she is dropping her egg during the night while roosting. Is there anyway to discourage that? It always ends up in a big pile of chicken poo.
