I was really sad to hear that your little hog didn’t make it, despite the efforts you went to. Sadly, not all hogs will survive hibernation, even if they had reached the necessary weight. It is a dangerous time for hogs. This year must have been particularly tricky for them, with fluctuations in the weather. But you did your best, and that is all we can do. Fingers crossed for the other two there.
I always look forward, but with some trepidation for the hogs to come back from hibernation, not knowing who is going to come back. This year I have had one little chap visiting all winter. The snow was a bit of a worry, but he was back after two days absence. The really cold weather before the snow didn’t seem to bother him so much. He made a nest here last year, but has mostly only used it for a naps and maybe a warm up in between snacking. By this time last year, the boys were beginning to return, but no sign yet. I don’t know what the little chap is going to make of it after being in sole occupation of the area all winter! He is beginning to forage already, so there must be a certain amount of wild food around now.
Good luck with the other hogs. I hope you get lots visiting this year.
