Sussex chicken: size, eggs and care guide

The Sussex is a standard-size breed laying about 240 to 260 cream to light brown eggs a year, with hens around 7 lb and roosters around 9 lb. The speckled variety gains more white flecking with each annual moult, so an old hen looks noticeably different from the pullet you bought.

How big is a Sussex?

A mature Sussex hen weighs about 7 lb and a rooster about 9 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.

Sussex egg production

This is one of the stronger laying breeds you can keep. A Sussex hen produces around 240 to 260 large cream to light brown eggs a year, roughly 4.6 to 5.0 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

Curious to the point of nosiness. Sussex hens follow keepers around the garden, investigate anything new, and are among the easiest breeds to train to a feed call. Friendly without being needy. Noise level is rated quiet to moderate, which matters if you keep chickens close to neighbours.

Origin and history

One of the oldest English breeds, with roots traced back to birds the Romans found in Britain. It was standardised in 1903 as the county of Sussex fought to keep its table-poultry trade alive against imported stock, and the speckled variety is the one most backyard keepers now buy.

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 Sussex 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

An unusually good forager that genuinely reduces its own feed bill given range. The flip side is that a confined Sussex gets bored, and a bored Sussex is one of the more determined escape artists among heavy breeds.

Feed cost for a flock of Sussex

Feed cost sits in the normal range for a standard laying breed: about 0.25 lb per bird per day, so six Sussex 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 Sussex right for you?

It suits free-range setups, gardeners who want company while they work, and keepers wanting a dual-purpose bird that lays well. It is a weaker choice for small confined runs where its curiosity turns into restlessness.
