Hi Al Bino
I see you haven’t had a reply yet, but the best thing to feed hedgehogs with is either hedgehog food – there are various types easily available online and in some pet shops – or meat flavoured cat/dog food, in jelly not gravy and not fish flavour. You can also offer them kitten biscuits. It is very important to leave them some water as well – they drink quite a lot.
If you have cats around you will find tips on this site for making feeding stations to, hopefully, exclude them – some more successful than others! But some of the hedgehog foods are less attractive to cats than others.
Good luck if you decide to try that, but another thing you can do to help hedgehogs is to try to make your garden more hedgehog friendly – again, there are lots of tips on this site.
