Hi MICKJAM
It might be a female with youngsters. They do sometimes come out during the day. The fact that it disappeared into what you think is a nest sounds promising. But keep an eye out. If the hog starts spending a lot of time out in the open, or looks as if it’s sunbathing or behaving strangely, then it might need help.
If you do become worried about it being out too long. You can find contact details of your nearest hog carer/rehabilitator from the BHPS on 01584 890801. You could explain what is happening more precisely to them and they will be able to advise you as to whether they think any action needs to be taken.
I’m guessing you have water around as well. That’s very important for the hogs 24 hours a day – exactly for this sort of situation.
