I just went out to give some greens to them and out hopped a black and white mini-me!
We put them in the greenhouse when the weather got very cold and they have dug absolutely huge burrows which must be where they were hiding it!
It has hidden again now and I can't see where it could be. I am wondering how old it is and if there are more in there!
I can't believe none of us have noticed this before - we go in there at least twice a day!
