Migrant problem

Just collecting our eggs this lunch time and noticed some animal had started a burrow by the hedge and not far from from our run. I think too small for a fox, no droppings so escaped rabbit or rat. What do you think. My birds got very excited when I went out with the camera, between the showers and Sandy got herself in the picture 

I would say it's a rat hole.

Could be an old rat burrow the hens have excavated.

If you are lucky !

Well it didn't take up residence . I filled in the hole next day and all is well. We are quite used to rats here,  usually getting the odd one paying us a visit as our property is right next to the canal . I don't usually bother too much about them as they are on their own. If we had a pack visiting then that would be different , and of course we never leave any food out.
