Hi Palladium
I usually keep putting food out until well after I’ve seen the last hog, in case. Some of the males may start to disappear for hibernation soon, but the females usually go later and often hoglets seem to appear from somewhere at this time of year. I normally find the hoglets go to hibernate latest and last year one here didn’t hibernate at all. There couldn’t have been much food around, but he visited here every night, often in sub zero temperatures. He only missed a couple of nights when the snow was too deep!
Some people leave food out all winter in case a non-hibernating hog or one who has woken up turns up. I definitely would, at least, leave a source of water out which is accessible to the hogs all winter.
