Hi Steve
If the hoglets are weaned Mother will probably be trying to have as little to do with them as possible. When her job is done, she will have nothing to do with them, other than by chance. She will be needing to get herself prepared for hibernation, so they have probably been left to fend for themselves. I don’t know where you are in the country, but 240-265g sounds too light for them to survive hibernation. The one being out during the day is particularly worrying. It is a warning sign that all is not well.
If it was me, I would be inclined to try to catch them tonight, if you get the chance, so that they can go to be checked over tomorrow. Otherwise you are putting it off for another day, and with a cold night tonight. If you can’t, then please do contact a carer tomorrow and take advice.
Good luck.
