Quinckes are in the care of the CCG. They may have medicines like the Rc suppressants, or had their transplant surgery with kakuhou that stored small amounts of Rc cells, or something else alike.

Them being ablte to eat human food and their gray kakugan are the results from their Rc levels being between 600-900s. Ghouls have their Rc levels between 1000-8000s.

Personally: I need more chapters to check if their kakugan is always gray.
