Hi Dave024
A hog should be able to get through a 4inch square hole, but not if the thing the hole is in is too light and could move. I’m not sure what a poundland plant trough is like, but if it’s what I’m imagining, it would probably be too light and as the hog tried to squeeze in, the trough would move – which it sounds as if you are finding. Is it strong enough to, say, put bricks on top of it, which might make it harder to move? If it couldn’t move, the hog might find it easier to get in.
Some people use those see through plastic storage boxes, so that they can see the hog inside whilst it’s eating/drinking. But they would probably also need to be fixed in place somehow.
Good luck. I hope you find some solution which is safe and suits the hog. Happy hog watching!
