Hi I.i.lewis
Sounds like you need another hog box! I agree it seems unlikely a female would give birth with 3 hogs in a box. They may have been fairly young hogs (even though no longer hoglets) who were overwintered together and have continued to share once they were released. (Apparently hoglets being over-wintered in captivity – because they were underweight – find it less stressful if they share accomodation).
But if you get another hog house, they might move into that one instead and give you the chance to clean the other one out. But if there is the possibility of hoglets be sure the house is not occupied before opening.
Hogs will make several visits a night to feeding areas, so that may explain the various comings and goings. But also, cameras are not totally reliable re. checking numbers of comings and goings – there is always a gap between clips when a hog can sneak past. They can be surprisingly fast when they want to be!
It’s lovely that you have so much activity there to watch and fingers crossed for some hoglets (one way or another!).
