We have been watching our visitors for a few years now. We have three CCTV night vision cameras set up to see them coming and going. At the moment we have three feeding stations and one sleeping house. In recent weeks we have marked them with tippex which is harmless.
One spot is a large healthy male
Two spot sex not sure
Three spot sex not sure
Four spot (nickname speedy) sex not sure
X spot sex not sure.
These ones seem to visit every night without fail.
Others of course visit but we are usually in bed so unable to mark them.
All we can say is “that every hog is welcome and there will always be food and water available”.
Looking out for little and poorly hedgehogs now that the winter will soon be upon us and these need extra care and attention.
