Hi morganventura
It seems unlikely that a female would use the same nest she hibernated in to give birth in, or give birth in a shared hog house. So it seems likely that she would find somewhere else.
But, it’s unusual for them to share a house to start with, although they may have separate nests within the house. But also hogs often move nests even during the course of hibernation, so it seems unusual for them still to be using the same one this long after coming out of hibernation (not least because of the potential build up of external parasites). But, some hogs seem to like to be different! Are you sure they are still spending the day in the house, rather than just going in for naps between snacks? The hogs here often go into the hog houses for naps, but spend the day elsewhere.
Have you thought of getting another hog house which she might decide to use for a birthing nest?
Fingers crossed for some hoglets this year, anyway, whether she has them in your garden or elsewhere.
Good luck – happy hog watching!
