Hi RuthLloyd
I wouldn’t worry too much, at this time of year.
The hedgehogs may be re-familiarising themselves with their ranges. There are normally more males than females around at this time of year and they have larger ranges than the females.
But it’s also possible that hedgehogs may have emerged but haven’t really finished their hibernation so go back into hibernation for a while. It is known that hedgehogs emerge for short periods during hibernation and sometimes even change nests. Hopefully you will see some again soon.
