#1 – Chicken Sexer
No, it’s not what you think! Apparently, when chicks are born they are indistinguishable. In order to determine their sex, commercial chicken hatcheries hire professionals who separate chicks using a method called vent sexing. The person has to squeeze a little poop out of every chick, which allows them take a peek inside and see whether a chicken has a small, pimple-like bump. Existence of the bump indicates that chick is a male. It may sound disgusting, but it appears the job pays really well.
