Round here it's only a matter of time before the jackdaws block the chimney with a nest. I think you can get bladders to push up the flue and inflate, but this can/will cause a damp problem. A traditional firescreen will somewhat break up the draft. Our house had a pillow pushed up the flue when we bought it. We now have a wood burning stove, which stops the draft (draught?) lit or not.
