That’s great that the scattering food worked – hope that continues.
It is quite late for hoglets, but they could still be ok, especially if you are still offering food when they get big enough to ‘leave home’. It sometimes stays a reasonable temperature into November. But the main problem is finding enough food later in the year, so if you are offering food (and water), they have a chance of getting big enough to hibernate. Having said that, some hogs decide not to hibernate at all and don’t seem to mind the cold temperatures, as long as they can find enough food and water.
But hoglets don’t always materialise from courtship. Hogs spend a lot of time circling and huffing, but it doesn’t always lead to actual mating. Then even if it does, there are all sorts of other things that can go wrong prior to birth and/or in the nest. As you suggest – keep an eye on whatever happens.
Fingers crossed that isn’t rats in the hog house!
