Chick. 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. In-ovo sexing technology has branched into two categories, invasive and non-invasive.

Some of these technologies rely on measuring eggs (through spectroscopy, chemical assays, or imaging); they can determine a chick's sex within 3-13 days of incubation.

Sexing or gender identification [1] is the process of determining the sex of an individual animal.
