Hi Jane
Good to hear you have hog activity there. Sadly not all hogs will survive hibernation. It is probably the most dangerous ‘natural’ time for them. We just have to hope that all those we have got to know will return. But sometimes hoglets will move away from the area where they were hoglets, especially the males, I have found. So those are two possibilities. (But it follows that means hoglets from other areas, may move into yours). But also if the hoglets went into hibernation late, they might be a bit late coming out. So hopefully you will get more returning.
By the way, there isn’t a team as such, on the Forum – it’s just a matter of one of us other participants on the Forum helping others out. So we all help each other to help the hogs.
Good luck and happy hog watching.
