Hi Sean Regan
Sadly, it isn’t possible to see your images, but well done for helping the hedgehog out when you found him collapsed on your lawn. The best thing to do in such circumstances is to get in contact with a local hedgehog rescue (contact details can be obtained from BHPS – number at the bottom of this page) because there can in some circumstances be other underlying problems. But sounds as if this little hog was lucky.
There are, however, some things which ring alarm bells. You must have missed all the conversations about the dangers of mealworms to hedgehogs. They have an imbalance of phosphorous and calcium which can cause calcium to be leached from the bones. They are particularly dangerous for hoglets who can grow in a deformed fashion as a result of eating too many mealworms. There is some useful information about feeding hogs in this link: http://www.valewildlife.org.uk/wp-content/uploads/2018/04/Feeding-wild-hedgehogs.pdf But it is best to feed hedgehogs cat, dog or hedgehog food for supplementary feeding and only water to drink.
It sounds as if you are saying that you are keeping the hedgehog confined to your garden. If the hog is now fit and healthy it should be allowed to be a wild and free hedgehog. Hedgehogs need lots of gardens to enable them to forage for sufficient food. They can travel up to 2 miles in a night. But how did the hog get into your garden in the first place? Is it able to exit via that route?
