Good to hear you have hogs around again. Keep an eye (or an ear!) out for Snorty, that his breathing doesn’t get too bad.
It’s probably too late now, but it’s best not to clean out a hog house, whilst a hog is still using it – i.e. whilst it’s out during the night. Some hogs will just turn up their noses and leave completely. Also hog houses should never be disturbed if there is any chance at all that there might be young ones in there. The Mother might desert them, or worse. Hopefully none of that applies to Snorty.
Good luck and happy hog watching.
