In-ovo sexing

In poultry farming, in-ovo sexing is a chick sexing method carried out while chicks are still in ovo (Latin for "inside the egg"). There are various methods to determine a chick's sex in the 21-day incubation period before it hatches (born by emerging from its eggshell).

In-ovo sexing technology has branched into two categories, invasive and non-invasive. The first invasive technology to be successfully commercially introduced for poultry farming was bio-market detection through the Dutch–German company Seleggt in November 2018. Meanwhile, the non-invasive in-ovo sexing technologies have been introduced to the market by the German start-up Orbem and AAT, a subsidiary of the EW Group.
