Australorp chicken: size, eggs and care guide

The Australorp is a standard-size breed laying about 250 to 300 brown eggs a year, with hens around 6.5 lb and roosters around 8.5 lb. The black plumage is not really black. In direct sunlight it throws a green and purple beetle sheen that is one of the more striking things in a backyard flock.

How big is a Australorp?

A mature Australorp hen weighs about 6.5 lb and a rooster about 8.5 lb, with a typical standing height of 16 to 18 inches. That puts it in the standard class, which is what drives its feed requirement of roughly 0.25 lb per bird per day before waste, free-ranging or seasonal adjustments.

Australorp egg production

This is one of the stronger laying breeds you can keep. A Australorp hen produces around 250 to 300 large brown eggs a year, roughly 4.8 to 5.8 a week, and holds that rate consistently rather than in bursts. The annual moult stops laying for a few weeks and the shortest winter days slow it further, but a healthy hen returns to full output once daylight lengthens. To turn that into a monthly total and a dollar value at your local egg price, run it through the egg production calculator.

Temperament and noise

Quiet, even-tempered and notably unflappable. Australorps rarely panic, rarely squabble, and are among the least noisy standard breeds, which makes them a strong pick where neighbours are close. Noise level is rated quiet, which matters if you keep chickens close to neighbours.

Origin and history

Australian breeders took English Orpington stock in the early 1900s and selected relentlessly for laying rather than show looks. The result set a world record in the 1920s when one hen laid 364 eggs in 365 days, a figure that has never been comfortably beaten under the same conditions.

Cold and heat tolerance

Cold tolerance is good and heat tolerance good. The upright single comb is the part most at risk in hard freezes, so ventilation that removes moisture without creating a draft matters.

Does the Australorp go broody?

Sometimes. A broody hen stops laying and sits, which is a nuisance if you want eggs and a gift if you want chicks hatched naturally without an incubator.

Care specifics for this breed

The easiest breed on this list to keep alive and laying. Its one genuine requirement is space, because despite the calm reputation it handles overcrowding poorly and will start feather-picking in a cramped run faster than its temperament suggests.

Feed cost for a flock of Australorp

Feed cost sits in the normal range for a standard laying breed: about 0.25 lb per bird per day, so six Australorp birds come to roughly $21.19 a month at $22 per 50 lb bag. Free-ranging typically trims around 15% off that and winter adds about 10%. The feed cost calculator gives the exact figure for your flock size and local feed price, including bags needed and how long each lasts.

Is the Australorp right for you?

It suits almost everyone, especially suburban keepers who need a quiet bird that still lays near the top of the range. It is a weaker choice for keepers who want colourful eggs or unusual plumage.
