Chick-fil-A stops serving breakfast daily at 10:30 a.m. Breakfast hours typically start at 6:30 a.m. and end sharply at 10:30 a.m. from Monday through Saturday. Chick-fil-A locations are closed on Sundays, so no breakfast service is available then. Hours might vary slightly by location, but in general, if you arrive before 10:30 a.m., breakfast is still being served.
