chXout® is a trusted, dedicated provider of a reliable and accurate bird sexing service through DNA analysis for breeders and pet owners alike.

Bird gender determination was the very first service to be offered by chXout® when our rural idyll fortuitously led us to the sexing of peregrine falcons.

Knowing a birds sex can be important for breeding and health but also the management and conservation of avian wildlife. For a range of species and most hatchlings, gender determination from physical appearance is extremely difficult. 

 DNA analysis is a quick and reliable solution for determining whether a bird is male or female. The test is based on the amplification of W and Z chromosomes of the birds. Female birds carry one of each chromosome (ZW), while males carry two Z chromosomes (ZZ).

 Bird sexing is achieved through DNA analysis of the following suitable sample submission types:
