My almost 2 year old chicken who lives in our house with us, laid an egg 3 days ago and wants to hatch it. She is barely eating or drinking and she won't get off the egg. We removed the egg, tried moving her bed, and she still won't eat. Any suggestions?

This page had some interesting info, near the bottom, in the 'Hatching' section...
