Is there any way to discourage a crow from sitting on your roof, we have one that seems to have adopted ours, it annoys the dog no end and this morning at daybreak the thing was making a great racket right by my open velux window, I'm quite ready to shot the bloody thing.
That's an excellent idea chipchopper. Now to get OH to scaffold the side of the house so I can tie a balloon up there and spray some satsuma oil round the chimney pot. ;)
