Hi CrummyMummy
Great news about the new hog house for Christmas! Definitely worth putting it out now. Yes, some hogs do change nests and apparently sometimes build new ones during hibernation time. But also there are some hogs which decide not to hibernate at all and you never know when one might come across the hog house and welcome a new place to stay.
The best thing to do is to put a small amount of bedding inside the hog house and leave loads of supplies of potential bedding nearby which the hog can select for itself.
Don’t forget to always leave water available for any hogs, even during winter, just in case.
