Not everyone that works there works for the zoo. Earmark handles the food.
Call human resources
That is a charming question with an appropriate answer ;-) It would be a good idea to call human resources at the zoo to inquire also. Good luck!
Sorry, but local guides can't answer to your charming question. You must ask to the zoo authority to be satisfy.
That's a charming question :) Can't say. They must have various jobs, some of which may have a provision of starting young. I'm pretty sure there was a teen-aged girl who was (possibly volunteering) ushering in and orienting visitors in the rare birds exhibit.
