PLEASE don't offer food until the suggested post-regurge fasting period is up. His digestive system needs a rest in order to build back up. If you feed him too soon, he won't be able to digest and you'll get another regurge. That would be very serious at this stage. He doesn't know this - he only has instincts. You're the keeper and you have to behave responsibly on his behalf because he doesn't know any better.
And please don't interpret hunting behaviour as "needing to be fed". Corns are always on the lookout for food. You can't tell whether or not a Corn is hungry from its behaviour. In this instance, even if it is hungry, eating would do more harm than good.
