Why... would one want to risk using super glue when it likely causes more harm than good?You have two choices. You can repair the wound to the crop so she can again eat and process her food or you can choose to euthanize. Simply spraying the wound, unless it's a very small hole, won't get it to heal before she dies of starvation.
If you post some closeups of the wound, and do trim away the feathers, we can better suggest how to close the wound using super glue.
A third option, not available to very many folks, is a vet that could close up the wound.
Anyways I’m done here. Good luck with your bird OP.
