Hi Galadriel, Paul and Michael.
Thanks so much for all your help. Definitely something to consider there. I really am into wildlife etc and particularly take great joy from my little smallholding. I'm not sure I'd be able for the scissors though! The nettle heap seems very interesting, I might try that and see what happens. And today I bought 3 baby ducks which we are hoping will help the situation eventually. You're all such a lovely helpful bunch.
