I'm sorry about the hen.
You have received good information about her care.
I agree, the challenge will likely be keeping her hydrated/fed since the top beak is missing.
Some birds can learn to adapt all you can do is try. Tubing food/fluids would be the way to go if that's possible for you.
This thread may help you. It's older, but Miss Fluffy Bum made and even thrived. Every injury and situation is different though, but you might find the whole thread informational.
