Chickens will trash almost any plant given time, as even if they're not going to eat it, they're innately curious creatures and want to keep having a go.
When I kept chickens the only things that survived in their large pens were thistles, nettles and elderberry bushes.!
A friend had Japanese Knotweed in her garden - she build the chicken run around it - 10 years later - no JKW - the chickens had eradicated it!
