That’s really good news, Lisa. At this time of year, they do seem to like having naps in between snacks. Don’t worry if the hog house doesn’t get used as a nest for a while after this time. You were really lucky it was used so quickly. I had mine for a few years before a nest was built in it, although I had occasionally used it for feeding. They did a survey about hog houses last year and I think the results should be out fairly soon, so something to look out for.
Glad to hear you are enjoying seeing the hogs. If you aren’t already, you will probably be totally under their spell before long!
