A nest in the shed

I found this nest in my dilapidated shed on my allotment. According to my Observer Book of Birds' Eggs these are blackbird eggs. I hope they survive. It was such delightful weather and as I wasn't working I did a bit of long overdue weeding on my allotment. I also got mildly carried away in my own garden with a general clear up of old plastic toys in various states of distress. Phew!
