Who is a sexer?

A sexer is a professional in a hatchery who can tell a male chick from a female. Also known as chick sexers, they are employed to separate the genders as hatcheries have different feeding programmes for them: females are reared to lay eggs and males are bred for their meat. Big hatcheries sex chickens as they have no use for male birds who are killed almost immediately. A sexer is trained to tell the chicks apart by their physical appearance and vents.
