Once in a very great while one may be an egg eater. I have had that happen too. I sold her. I'm not sure if she continued the practice at her new place but she would be acclimating to it so maybe not as it would be a new environment. Otherwise if a egg is cracked the birds have eaten it but very rarely this happens. Maybe you could blow out an egg and put something very unsavory in the egg and see if she does it and maybe it will teach her a lesson. Just an idea. Good luck...
