Since posting… we now have two and by the looks of the late night action caught on camera, we may have a family soon! 🙂
Mr comes and goes but every night the other one comes out at dusk from under the shed. We have concrete fence bases and there are no access points into the garden from that side.
She has disappeared over winter in the past but I also didn’t put the camera out much so she may have been around. Food was not taken regularly.
There is a lot of rubble under the shed. I’ve had a good look but as there are. a lot of bricks and offcuts of stone, its impossible to see front to back.
Sorry, I know thats not very conclusive. We’re in no rush to move it and certainly would not while I had any signs she was still around.
It makes my night every night when she returns 🙂
