This morning the burrow had moved a bit, first pic the orig entrance is on the right new hole on the left, about half the size of the other Maybe they are all down there having a party
Yesterday morning we had a new burrow and extra holes in the garden, this morning we had nothing new. May set up a old mobile with time lapse app on it
It appears whatever it was has moved out, I put some hay/grass over the hole about 5 days ago and it's still undisturbed I will give it another week or so and dig the area
