Well it certainly sounds nicer for the hog being in your new hog house than in the under a bin covering the soakaway!
No it isn’t too early for hibernation, so the hog might have decided to hibernate in your hog house. No, best not to disturb the hog at all – you are thinking along the right lines! If you want to see if the hog comes out at night, you can always put a small twig, small rolled up paper ball, or the like in the entrance to see whether it gets moved.
Personally, I wouldn’t keep the food so close to the nest – it might attract unwanted visitors, but if the hog is used to it being there, if you want to move, it, I would move it gradually. Water is really important 24 hours a day every day, including winter.
The only other thing you might want to do is make sure there is plenty of nesting material around. Sometimes hogs make new nests during hibernation time. But sounds like you are doing a pretty good job. You’re so lucky to have a hog move straight in to your hog house!
Good luck. Fingers crossed for a successful hibernation.
