Hi Amanda
The trouble with hogs is that you can’t always tell that they aren’t well unless they are very unwell. When you say it’s out during the day, do you mean amongst vegetation or right out in the open? In vegetation is probably ok, but if a hog is right out in the open (sometimes described as sunbathing) that is not normal and it needs help. I wasn’t sure from what you said whether the hog was definitely a female? If so, as you suggest it might have hoglets somewhere.
Sounds as if you are doing a really good job spreading the word. I wonder, did the developers make hog holes in fences, etc.? If not and they are still developing the area, maybe they could be persuaded to do that. Here are a couple of links which might be helpful.

Good luck with your article and the hogs in general and hopefully some hoglets soon!
