Spent some time yesterday, in between outdoor gardening jobs, when it got too hot, clearing the outbuilding out (can't bring myself to call it a workshop yet...) to make space for my mate to finish the electrics.
Shifted the scaffold tower up into the storage loft only to find this in between two of the boards that had been stacked together.
The door has been open for weeks so the owner must have found its way in and built the nest and laid in it.
Issue is, I was blissfully unaware until yesterday, and I shut and locked it up when we went on holiday to New York week before last...
The owner must have been out so I imagine the eggs haven't been sat on for 2 weeks now so I imagine they are no more!
I've left the door open again just in case mummy wants to return but I'm skeptical.
Anyone got any idea what it might be...?
