Thanks I will tell her. Oh I've never heard of cork wood. Will have to look it up and see if it can be grown here. The chickens are just eating machines especially Ginny the Amber. Anything and everything goes in her mouth. She really is a chicken dustbin!! I have a monkey puzzle tree a little further round in the garden that you can't see in the pic, now that is one thing they do stay away from as it's very sharp and prickly!! It's drawn blood on me quite a few times when I've been weeding.
