I would put the food and water somewhere else – there may be other hogs coming for the food and water, too. But it could also attract predators. So I would always keep feeding and nesting/sleeping boxes separately. Having said that hogs are quite capable of deciding they want to build a nest in a feeding box!
But, I would leave her to bring up her young in peace, without the potential of other hogs turning up to eat next door.
Good luck. Happy hog watching and hopefully happy hoglet watching later on!
