I've dealt with cracked beaks. Carefully and gently use a Q-tip to dab betadine on the beak, then apply a light coating of neosporin if possible. Eventually a new beak will grow but it takes time, depending on the severity of the injury.
Your bird will not be able to eat normally, ie, pick up feed with her beak, therefore she could starve and dehydrate.
This will be long term treatment and care. She will need to be put in a cage, provide a perch for her so she can sleep at night. Keep the cage as clean as possible.
You'll need a deep bowl for her to be able to eat/drink at all times. The reason you need a deep bowl is that you dont want her to peck on or at a hard or solid object or surface which will cause further injury and pain.
Put feed in the bowl and add water. You want a watery consistency at all times. This will be her only source of water to drink. Check the consistency several times a day because the feed absorbs alot of water and dries out. You'll have to add water to keep it a watery gruel continuously. Change out the mixture daily, it must be kept fresh in order for her to eat.
Initially, to encourage her to eat the gruel, you can add several bits of dried mealworms on top of the gruel to get her used to eating from the bowl.
Only you can determine if there's improvement. I'll give you an example: After 2 weeks put several grains of cracked corn on the bottom of the cage. Closely watch and see if she can pick them up and swallow them. If not, keep her caged for another week.
Then repeat with the cracked corn test the following week. If she picks the cracked corn up and then drops them, she's not healed and needs to be kept caged until the beak has either healed or the new beak is in place and is able to pick up feed and eat normally. Only then you'll be able to release her.
In your case, I'd wait 3 weeks before giving her the 'cracked corn' test. It looks like her injury is severe. Good luck. Be attentive and have patience.
One last thing, never use super glue for beak injuries. Unseen nerve endings are involved not to mention the possibility of the non shedding of the old beak due to the glue.
