As RC pointed out, one lash egg on its own doesn’t mean a death sentence, if you have some amoxicillin I would dose her for a week with that, after all it is an infection, and treating it as such will give her a good quality log life.
Nothing is guaranteed, she could be killed by a fox, or hawk. There are plenty of hazards out there for the chooks.
