Hi Leekay62
Yes, it’s possible the females are off somewhere giving birth. But it isn’t reallly strange that there have been signs of courtship but no hoglets. There is no certainty that courtship will lead to hoglets and even if some are born, there is a high mortality rate. Then if hoglets are produced, Mother hog may take them, when they first venture out, to somewhere else in her range, especially if she knows several males tend to visit your garden. But hopefully some will eventually turn up. Fingers crossed!
Good luck.
