Chapter 1: Appearance of Sussex Chickens

Sussex chickens have a sturdy, well balanced build with broad chests, upright posture, & soft feathering. Their alert expressions & confident stance give them a classic barnyard look. They are medium heavy birds that hold themselves with calm, steady presence in the flock.

Clean legs, single combs (except some regional varieties), & full tails complete their signature profile.

Size

Sussex birds are medium heavy dual purpose chickens. Roosters average around 9 lb, hens around 7 lb. Their size makes them substantial but still agile for foraging.

Colors

The APA recognizes several colors, with Speckled, Light, & Red being the most common. Light Sussex have striking white bodies with black hackles & tail feathers. Speckled Sussex feature rich mahogany feathers sprinkled with white speckles that increase after each molt.

 

Chapter 2: History of Sussex Chickens

The Sussex breed dates back to ancient Roman Britain & became formally recognized in the 1800s. For centuries, they served as classic English farm birds—used for eggs, meat, & exhibition.

Their versatility made them one of the most important dual purpose breeds in England before commercial hybrids rose to prominence.

 

Chapter 3: Sussex Chickens for Sale

You can find Sussex chickens through hatcheries, farm stores, homestead breeders, & specialty lines focusing on Speckled or Light varieties. Hatchery strains are widely available, while breeder birds may show stronger color & type.

Look for bright eyes, clean legs, & active behavior when selecting chicks or older birds.

 

Chapter 4: Sussex Egg Laying

Sussex hens are dependable layers of large brown eggs, averaging 240–275 per year. They begin laying around 20–22 weeks & produce steadily through much of the year, including cooler months.

Their calm nature helps reduce stress related dips in laying.

 

Chapter 5: Sussex Health Issues & Care

Sussex chickens are hardy & adaptable with no major breed specific issues. Their thicker plumage can hide mites if not inspected regularly. They thrive with routine care: clean coops, balanced feed, & fresh water.

Because they are friendly & willing to be handled, monitoring health is straightforward.

Health Issues

Check around the vent, under wings, & at the base of feathers for lice or mites, especially in speckled or darker varieties. Provide dust bath areas & maintain dry bedding.

Climate Needs

Sussex chickens handle cold extremely well thanks to dense feathers. In heat, ensure shade & ventilation to prevent overheating. Their single combs can be frostbite prone in very cold, damp weather, so ventilation is key.

 

Chapter 6: Sussex Temperament

Sussex chickens are calm, curious, & people friendly. They enjoy following you around the yard, investigating new things, & staying involved in flock activity. Their gentle nature makes them excellent for families with children.

They integrate well into mixed flocks & rarely bully smaller or more timid breeds.

Temperament

Broody Sussex hens tend to be patient, even tempered sitters. Even when not broody, Sussex maintain friendly and cooperative behavior year round.

 

Chapter 7: Feeding Sussex

Start chicks on a 20–21% starter, transition to a 16–18% grower, then feed a 16% layer ration once hens begin laying. Sussex birds forage well, helping reduce feed costs if given space.

Provide grit & oyster shell separately. Avoid excess treats to maintain healthy weight.

 

Chapter 8: Coop & Run Size for Sussex

Provide at least 4 square feet of coop space & 10–15+ square feet of run space per bird. Sussex enjoy both confinement & free ranging, staying active without being flighty.

Use standard 12x12 inch nest boxes & roosts 18–24 inches high for their medium heavy build.
