Last night my main intent was to verify the hedgehog(s) were eating their food (from the feeding station).
And I recorded some behaviour that I found surprising and don't understand. On a gravel area the hedgehog seemed determined to lick one stone (but a few others picked up in his/her mouth). The area was not baited beyond the hedgehog feeding station a few feet away (and no food or debris from that. Water dish a few feet away.
Gravel area is occasionally walked on but beyond that nothing except (maybe) worryingly a month ago it was glycophosphated and nt much rain since then.
(Might take a bit of time to load as it's HD @60 fps and hosted on my site NOT a dedicated video hosting site as they tend to over-compress and mess up quality ...)
Any ideas as to why? I wondered about mineral needs but I'd guess they should be fine from their normal diet (and plenty of insects and beetles around and the moment)
Somebody had been eating in but only a bit each night. In previous years a daily task was to clean out the poo left by the previous night's visitors. But this year it's all clean and I was a bit concerned that I might just be encouraging local rats.
Part of our back garden is the same surface as in your video and the hedgehog(s) nose and rootle in the stones but I have never seen them lick any of the stones.
As you said this behaviour was surprising, I'm guessing you have not seen it before. Since the area was treated have you recorded any other hedgehogs? If so, then it seems unlikely that this hog was attracted to the glyposate.
It appears to be in the process of self- anointing which still is somewhat of a mystery, however it’s sometimes happens when they encounter a smell they don’t recognise so they lick the object which induces saliva to form which they spread over their body. So it could be done as a type of self – defence e.g. the hedgehog is using the smell to mask its own whereabouts.

Sorry I can't help.

Not seen it before but I would probably not have as I've not tried to record the hedgehogs round the feeding station before (normally set camera in more remote parts of the garden). Only reason this time was to check it was the hedgehogs taking the food from the feed station rather than my encouraging rats. Somebody visits the feed station thing and takes food most nights.
This year there are certainly at least two hedgehogs as I've seen two together at the sam time (having a minor scuffle). Seen hedgehogs in other parts of the garden but may easily be the same ones as I don't recognise them by sight (yet?).

That would fit with the bending round and licking its hind quarters after the stone licking.
