Hi Delport
I’m so sorry to hear this, it’s heartbreaking to see dead hedgehogs anywhere.
Nic has replied fully to your questions but I’d like to add it’s a good idea to feed year round if in much smaller quantities as sometimes hogs wake & need a top up during the colder months & will remember there’s a reliable source in your garden. If the food is in a feeder so cats can’t get it then Smilla kitten biscuits (online from Zooplus) are a cheap & good food to leave out along with water & any uneaten in the morning will be enjoyed by any corvids or pigeons visiting.
Hopefully you’ll have some hogs this year & your nest box will be used, mine is awaiting an occupant too. My hog visitors returned a couple of days ago & are tucking into Smilla each night again. Good luck.
