That’s good that the hog seemed well. Keep an eye out just in case. (I’m assuming you meant 12.30 in the day?) It’s possible at this time of year that a female with young could be out and about during the day, but also possible for an unwell hog to be. A female with young would probably not hang around too long and would move purposefully. If the hog is looking lethargic, wobbly or seems to be sunbathing or if you are ever worried about a hog you could ring BHPS on 01584 890801 to get the details of your nearest hog carer/rehabilitator and take their advice.
