autosexing
LowTechnical (agriculture, aviculture, genetics)
Definition
Meaning
A method in poultry breeding and genetics where the sex of newly hatched chicks can be determined immediately by their plumage colour or pattern, without vent sexing.
The characteristic or genetic trait in certain breeds of poultry (and some other birds) where males and females exhibit visibly different down colour or feather patterns from hatching, allowing for easy, early, and non-invasive sex determination.
Linguistics
Semantic Notes
Term is highly specialized to animal husbandry and genetics. It is a compound noun ('auto-' + 'sexing'). Do not confuse with automated sex-sorting technology (e.g., in eggs). The focus is on an inherent, genetically programmed phenotypic difference.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning or spelling. Usage is identical in technical contexts.
Connotations
Neutral, technical term in both varieties.
Frequency
Equally rare and technical in both dialects, confined to poultry-keeping and genetic communities.

Usage
Context Usage
Business
Used in marketing poultry breeds to smallholders and commercial farms, e.g., 'Our autosexing layers save labour costs.'
Academic
Used in genetics and animal science papers discussing sex-linked inheritance and poultry breeding programmes.
Everyday
Virtually never used outside of dedicated poultry-keeping communities.
Technical
Core term in aviculture and agricultural genetics for describing breeds like Cream Legbars, Cambars, or certain crosses.
Examples
By Part of Speech
adjective
British English
- We specialise in autosexing poultry breeds for the smallholder.
- The autosexing characteristic is clearly visible in the day-old chicks.
American English
- She ordered an autosexing variety of chicks for her backyard flock.
- The autosexing trait is a major advantage for rapid sorting.
Examples
By CEFR Level
- Autosexing chicks have different colours when they hatch.
- The breeder chose an autosexing breed to avoid the difficult process of vent sexing.
- A key benefit of autosexing is that it prevents the unnecessary rearing of unwanted male chicks in layer flocks.
- The autosexing mechanism in Cream Legbars is based on a sex-linked silver/gold gene that manifests in distinct down colours.
- Modern poultry genetics has refined autosexing techniques to create more efficient and welfare-friendly production systems.
Learning
Memory Aids
Mnemonic
Think: 'AUTOmatically telling the SEX of a chick just by looking at it.'
Conceptual Metaphor
GENETICS IS A CODE; The colour is a read-out of the sex chromosome code.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation like *автосексинг*. Use описательный перевод: 'определение пола по окрасу пуха/оперения' or 'аутосексная порода'.
- Do not confuse with автома́тическое определе́ние пола́ (which implies a machine).
Common Mistakes
- Misspelling as 'autosexing' (one 's').
- Using it as a verb (e.g., 'I autosexed the chicks' is non-standard; prefer 'I sexed the chicks using autosexing traits.').
- Applying it to species other than birds where it is not a standard term.

FAQ
Frequently Asked Questions
It is highly accurate (typically >95%) when breeding protocols are followed correctly, but occasional mis-marked chicks can occur due to genetic variations.
No, it is a specific genetic trait found in certain breeds or purpose-bred hybrids, such as the Cream Legbar, Cambar, or some Rhode Island Red crosses.
No, it is a completely non-invasive method as it relies solely on visual observation of natural colouration, unlike vent sexing which requires physical manipulation.
They are closely related. All autosexing breeds are sex-linked, but not all sex-linked traits result in autosexing (day-old visible difference). Some sex-linked traits only appear in adult feathering.
