Hi
Sounds like a female nest building. They are sometimes still out during the day. You could make a bit of straw/hay available – it’s her choice whether she takes it or not. But she may already have finished building.
Good news that your neighbours aren’t going to move anything.
Assuming that the hog is about to give birth, the young might start venturing out with Mother after about four weeks, but you might not see them until they’re a couple of months old.
Make sure you leave a source of water available all day every day. If you have somewhere in the shade that would be handy. She might pop out for a rest from the youngsters and welcome a drink. Especially if it’s hot. If you normally offer food, I would continue with that, also – at night. The mothers sometimes go out during the day for a break, when they have young ones, but are likely to be under vegetation, rather than right in the open (unless it’s to access water).
Good luck. Fingers crossed for them.
