We have processed thousands of DNA samples for the gender determination of birds from a range of species (Bird Species List).

The falcon breeding season is a particularly busy time for all involved, running from late April until July. We have developed a new service exclusively for breeders to help them manage their time constraints and busy schedules. Our new 1-working day turnaround service (£40 incl. VAT) is ideal for those who simply cannot wait to find out the sex or simply do not have the time!

This season alone we did ~2000 samples for a range of clients, whether you are a big breeder, small breeder or simply wish to know gender of a pet, get in touch today!
