Hi Aggie
Sometimes it take a while before hogs will take to new houses, so don’t be too worried if one doesn’t move straight in. At least they will be there is a hog decides to move house later on. I wouldn’t move them around if they don’t immediately get used – give the hogs a chance to get used to them being there. If you want to find out whether any hogs are going in or out without disturbing them, you could put a small twig, piece of straw or ball of paper, or similar, in the doorway and see if it gets moved.
