That’s brilliant. I caught my hardy winter hog on cam building a nest last year, when he was still quite young. Two nights running, like clockwork, he started work at 5a.m. It’s fascinating isn’t it. Amazing how much material they can carry in their mouths at a time and I loved the moustache effect! If Mum knows there’s food there, I’m sure she’ll keep visiting. It is normal for them to separate when the youngster grows up. Sometimes the male youngsters move on somewhere else after a bit, but I have found that they tend to visit from time to time, especially to start with.
