Thank you for your answer, yes I’m sure she’s a female because I can see the “button” on the males bellies every time they drink from the bowl. The net on the background of the video is strategically placed to force the hogs to show their profile to the camera whenever they drink so it’s very easy to sex them.
Yes it’s probably the rubbing behavior, I’ve seen her do it twice and I was worried it could be something abnormal but apparently it’s nothing to worry about.
About the marked hedgehog I doubt it’s a man-made id mark: nobody in my area cares about hedgehogs (sadly in my country hedgehogs are just street pizzas that sometimes materialize on the asphalt). I’ve seen the marked hedgehog under the light once and nothing was visible on his back to the naked eye. The only thing I can think of is that maybe he self-anointed with something that appears funny on the IR light.
I also confirm that the things on the hedgehog face is dirt/soil debris and not fleas. I found out that it’s always the same female using my hedgehog house: sometimes she’s clean, others she’s not.
