Some advice please. Last year a bird nested in my potting shed down the bottom of the garden. I ended up with bird poo all over my lawn mower and the sad sight of dead baby bird fallen from the nest. Plus I got divebombed every time I went in there!
The door has a little gap where they are getting in (difficult to fix without spending a fortune) and this year I've noticed them swooping around the door again. They are black with pointy wings...very fast...a Swift maybe? I have strung up CDs by the door to put them off.
Is there anything else I can do?
