@alinas2010 gave you excellent advice. Read the article. Carefully follow all the instructions in it.
Your patient's woes did likely start with the huge egg. Was it a double yolk by some chance? Rather than being a bonus, a jumbo egg doesn't do the hen who has to lay it any favors, though. It increases the likelihood of chronic egg binding and a high risk of death.
After this prolapse finally resolves, continue giving her one calcium tablet each day for the next two weeks. This can help to tame her ovulation to a single ovum if she's in the habit of double yolk eggs.
