Why would an African Grey after 10 years lay 2 eggs?

Our African Grey is about ten years old. We also thought the bird was a male until, about one week ago. She has two eggs now and we don't know how to take them away from her. She's getting very mean because of these eggs. Do we just take them and let nature take it's course or put something else in it's place???? Thank You, Kim---can't wait for an answer
