Thanks for that, I do not want to keep them in as they add something to the top of the garden and I find them very entertaining, I think my dog helped them break loose, she chewed the bottom of a wooden gate and after getting threw that, they decided the flowers were very appealing, on that subject, do you know any plants they do not like to eat, my shrubs are fine but they have eaten my ferns as my top garden is a bit like a woodland area and now I have just a few bare bits that could do with something.
