Well done feeding the hogs. Sounds as if they might be youngsters if they’re sharing the hog house. I agree with LalaBlanca about the nuts. I would cut them out and just stick to the hog food, which hopefully should have the correct balance of phosphorous and calcium.
Ideally, in the long term, the best thing for the hogs is if we all try to improve the habitat in our gardens and link them, of course, so that the hogs can find natural food for themselves without us having to supplement it. Linking gardens has the added benefit that hogs don’t have to cross roads so often, which has to be a good thing.
Good luck with the hogs there, they might go off to hibernate soon, so enjoy watching your camera images, until then.
