Sorry for your poor little girl~ouch! Yes more photos from different angles would definitely help for everyone to see better what she’s got going on.
Beaks can heal. It’s hard to see exactly how bad the injury is.
Soft feed. It’s very painful to try and eat with a beak injury so soft food should be offered and you should monitor her to see that she is actually eating.
You could soak her regular crumbles/pellets and make a oatmeal-like consistency. Scrambled egg or anything wet and mashed easy to lap up until she heals.
Chickens have a unique way of trying not to call attention to themselves when they are sick or injured so... she may ACT like she’s pecking or eating when really she’s just going through the motions (trying to act normal). You might want to separate her to watch how she manages with food and water. And to See how much she is eating.
