What is a Sex Link Chicken?
Sex link chickens are a type of hybrid chicken breed. Hybrid chicken breeds are the result of cross breeding two or more heritage or purebred chicken breeds, usually to produce offspring that lays more eggs, produce more meat or other desirable traits like plumage colour, body shape or temperament.
Sex link chickens can be sexed by their dominant feather colour on the day they hatch. In hatcheries and egg farming operations, this makes it easy for farmers to separate the males from females. As a backyard chicken keeper, it means that you can be pretty certain that the chicks you are purchasing from your breeder or hatchery are indeed hens, and you won't have to figure out what do with unwanted roosters as your baby chicks grow.

Unlike hybrid sex link chickens, mating auto sex chickens will produce chicks that display the same gender revealing characteristics. There are only a few purebred and heritage chicken breeds that are autosex chickens, and these breeds are rare or in some cases, nearly extinct. These include:
