Apologies for not being around till today
Hi and welcome to WAB Rha
Looking at your photograph it could be mites. If you look closely at the ear under a magnifying glass - does anything appear to move? They usually congregate around the ears and eyes and look like tiny grains of sand.
If nothing is moving, then it could be ringworm, or a type of skin infection that may require antibiotics. The only way to know for sure is to capture the
Hedgehog and take it to your local rescue centre or a Vet who will examine it under a special light source. If it is ringworm then please make sure you keep the
Hedgehog confined seperately and wear gloves as it is contagious to humans and pets.
It is curable whichever problem it turns out to be, so please do get it treated as soon as possible.
