I have an Ameraucana that was attached by a dog 3 months ago. She is still unable to walk. I still have her in a sling. My problem is her upper beak has overgrown the lower by almost 1/2 inch. It is starting to impede her eating process. I need to trim her beak to enable her to eat without issue. I ONLY want to trim, I do not want anything permanent. I do not want to harm her, she has wiggled her way firmly into my family and want to make it easier on her. Any help would be greatly appreciated.
