Now surely you have experienced once in your life a rotten egg that explodes lol. If not... if I was her I would pick that bomb up and march it right out. Lol And if it does explode, it takes weeks to get smell gone just like skunk. Smart girl. Giving her credit just in case she has gone carnivore! I had a rhode island do this once to me. She had to have absolute quiet, darkness and peace and she did not like sharing her eggs! After about a dozen, she actually moved 5 eggs in her nest to nearby bushes. High real estate. She had her little dust hole turned nest, water, and the privacy of her bush. She was so sweet.
