Hi fastilly
Welcome to the forum!
I had a look at your video, but unfortunately wasn’t able to tell whether it was a male or female – it was scratching too quickly! But you may be able to tell yourself from other videos. The males have a ‘blob’, roughly mid-abdomen, about where you might expect a tummy button to be.
It isn’t possible to tell weight with any accuracy from images, although knowing the size of the feeding dishes might help to estimate the size. However, it is really too early to worry about size for hibernation – there will likely be hoglets not yet born who will be able to put on sufficient weight for hibernation. Having said that, looking at this hedgehog, I wouldn’t be worried about its size for hibernation. Younger hedgehogs heads tend to look bigger in relation to their bodies – although photos/video can be misleading. It will help that you are offering supplementary food – water too, hopefully.
Good luck and happy hog watching.
