Yes I have an update.
3 nights after the initial visit I had a hedgehog visit the garden. He wasn’t one of my residents but often came through to eat. He was recognisable but a bleached area on his back. The next morning one of my neighbours called me to say that a Hedgehog was dead in one of the driveways mauled. It was the Hedgehog I’d seen visiting and the marks, blood stains and scratches were typical of a badger. For a week I saw no more Hedgehogs and I believed them all to have been taken. This has not turned out to be the case though. The two remaining resident Hedgehogs had gone back into a mini hibernation which I think is a defense response when a predator is visiting their territory regularly. So I still have 2 resident Hedgehogs, I’ve stopped any possibility of badgers being able to access my property but they still run the risk of being attacked outside the boundaries of my garden. I hope of course the Badger has moved on but nature is nature and I cannot intefere.
