I think trimming will help her continue to eat well.
I kept a cross beaked Orpington for several years that had similar looking issues.
It was easiest for her to eat wet feed. I simply soaked the normal feed in hot water for about 10 minutes then served it up. It should be the consistency of cooked oatmeal, not to wet and not to dry. I still give wet feed every morning even though my Orpington has passed away. My entire flock seems to enjoy it.
