A young blackbird is busy making a nest in my polytunnel sized log store. The structure is built and she's starting to line it. I only discovered it today. I suspect rats under the shed next to it. They'll easily get at the eggs when she lays. All this is happening under an oak and there are squirrels in there too. Poor thing doesn't stand much of a chance tbh.
Is there anything I can do or would it be better to let nature take its course here?
She's very tame and comes within a yard of me when I'm in the garden without the dog.
