Bird egg in garden š„š£

Hi everyone

We have been trying to make our garden more wildlife friendly and I have noticed that we have what appears to be a bird nest in the garden on top of a bush next to our monster laylandii.
We have visiting dunnocks, robin, bluetits, blackbirds and sparrows. From looking online I think this may be a dunnock egg? It's so small! I assume from the state of it that it is damaged and has been abandoned for some reason? Is this a sign of a problem or just nature?Ā
Very curious as to why they have chosen such an open spot to build a nest?! I'm surprised such a small bird was able to use such big pieces and I've not noticed them building. Looks like they have picked up some laylandii cuttings to use but is there anything else I can put out to help with the building process? Would love to see some baby birds in the garden this year!Ā

That doesnāt really look like a birds nest to me ... unless the foundations of a magpieās nest maybe ... which might explain the stolen and eaten egg from a smaller birdās nest.Ā
Gardening in Central NorfolkĀ on improved gritty moraine over chalk ... free-draining.
Will keep monitoring and watch for any magpies but I have not seen any visiting! Sneaky!

As for the egg it's about the size of a thumbnail @Skandi so perhaps it's been moved there by something else?Ā In person it's a very pale blue. I've zoomed in and it looks yellow inside.
