History & Origins
Australorps bred from Black Orpingtons imported to Australia, selected for egg production without sacrificing meat quality. A hen laid 364 eggs in 365 days in 1920s official testing — a record still celebrated. British Australorp clubs maintain standard type against industrial hybrid pressure. Quiet temperament suits neighbours concerned about crowing.

Australorp Common Health Issues
Conditions seen more often in this breed, and how owners and vets help manage them. This is general guidance, not veterinary advice — always speak to your vet.
Heat stress
Black plumage absorbs heat in rare extreme British summers.
Care: Shade, frozen water bottles in runs and improved coop airflow.
Obesity
Heavy frame gains weight on treats without exercise.
Care: Layer ration matched to activity; scatter feeding enrichment.
Red mite infestations
Coop parasites reduce production and cause anaemia.
Care: Integrated pest management for coops and nest boxes.
