Chickens with cross beak can still live relatively normal lives, don’t worry, they just need extra care. Deeper feed and water bowls are a good thing, but at yours age and size, and the fact her beak isn’t so bad yet, that’s probably not necessary yet. When it does start getting worse, i suggest mixing her feed with water if she struggles with hard food. I have a cockerel with cross beak who struggles with hard feed, but when it’s mixed with water to a mushy consistency, he eats very well.
