I put half a boiled egg out for the hedgehog and he arrived again on 10th April 2021 at mid-morning to eat it up.
I then worried about him turning up in daylight and after contacting the rescue centre again I decided to stop leaving food out in the morning and only leave it out in the evening, and to get some dog or cat food for it!!
Here is a photo of the hedgehog enjoying the boiled egg in case the video does not work.
