Yup - depends on the individual. Some will wuff it straight down the minute they see it regardless of where they are, some like to be left alone in the dark overnight and won't eat if they're watched. Can go for adults as well as hatchlings. Feeding habits are an individual preference that you just have to work out for each one as they arrive.
And as bkelm18 says, they can change during their lives. Nothing's ever simple with a Corn Snake!
