The minimum age that you have to be to work at or get hired to work at KFC is 16 years old.
If you're under 16 years old then KFC will not hire you to work there.
As long as you're 16 years old or older you can be hired to work at KFC.
My sister got a Job at KFC when she was 16 and she continued to work at KFC until she turned 21 years old.
Then by that time she had went through college and went on to be a nurse in a hospital.
She now gets better pay but working at KFC did help her pay her bills and helped her get through college.
KFC is a pretty good place to work at least for your first job and then if possible you should work on finding another career that pays you more money per hour for your time.
