My blue ringneck has been behaving very odd over the last few weeks, and tearing up the newspaper I put at the bottom of her cage, and then snuggling under the paper. A few days ago, she laid an egg. She is alone in the cage - I do not have a partner for her. Now I am not sure if I should remove the egg or how I should treat her. I have had her for approximately 3 years, my ex husband for about a year, so she is not an old bird.
