When a female parakeet is preparing to lay an egg, she begins to prepare a nesting area by shredding bedding or newspaper and gathering it together. Her behavior also becomes more playful and affectionate.

According to Tailfeathers Network, other signs that a parakeet is getting ready to lay an egg include holding her tail straight up in the air, developing white rings around her eyes, having an increased appetite and possibly gaining some extra weight. A female parakeet does not need a male parakeet to lay an egg. She needs plenty of calcium while preparing to lay an egg, and her keeper must watch her closely for signs of distress.
