chXout are a trusted DNA testing service provider, dedicated to providing breeders and pet owners alike with accurate and reliable DNA testing.

For a range of species and most hatchlings sex determination by their appearance or physical appearance is extremely difficult. Therefore, DNA analysis presents itself as the most viable solution for determining whether a bird is male or female as the sexing polymerase chain reaction (PCR) detects DNA sequences in the avian sex chromosomes; male birds (ZZ) and female birds (ZW). Bird sexing is achieved through DNA analysis of the following suitable sample submission types:


Dry Egg Membrane

Plucked Feathers

Mouth Swab

For more information on suitable sample submissions types and their collection, please visit our Sample Submissions page.
