They will use hides most of the time, in my experience, except when exploring around or if they find what they think is a hidden perch somewhere. Just the exploring is more often than a BP. They often peek out when they feel you come into the room once they're older/more confident (I see it start around 6-12 months on mine so far).
Generally, much easier going snakes. Hunger strikes besides a single skipped meal or something due to a shed are fairly unusual if their temps are in a good range. They will fast as part of brumation if you do that, but it isn't needed unless you are breeding, so there shouldn't be a fast in winter.
Generally, even slightly off temps (within 5 degrees) don't seem to put mine off food, so I would guess that if you get a lot of rejections that something is wrong somewhere.
Don't feel dumb! It is good to check and after so much with BPs, it really does seem too good to be true. The super easy husbandry and tendency to be great eaters and hardy is what makes the corn snake the other most highly recommended beginner snake (the other being the ball python of course.)
