Glad you asked. Essentially a Chicken Sexer goes to the hen houses and sorts the baby chicks by sex. That’s pretty much it. I assume you need some sort of “what does a baby chick penis look like?" training for this dream job.
As far as pay goes, you won’t be retiring to Boca, Fl anytime soon. You make around $300 per week / $15,600 per year (depending on if you work X-mas week).
