Hi JMG
Size isn’t a reliable indicator of male or female i.e. some females are larger than some males. But some of the hogs have probably started hibernating already, so they may not return this year. If they are males they tend to hibernate earlier and to come out of hibernation earlier than the females, so keep an eye out for them late winter/early spring.
I would keep feeding, in case, as often at this time of year hoglets seem to appear from somewhere. Possibly other people have stopped feeding. The hoglets are often around even after all the adults have disappeared. Some hogs decide not to hibernate at all and some might come out of hibernation for short periods and welcome a snack. Definitely always leave a water source out all day every day, all year round.
I hope the hogs are back next year, if not before.
