It is true, most hens will continue to replace the eggs if you remove them. Do you know if this is Jeremiah's first clutch? Hopefully this will be a one time event. Where did she lay her eggs? I would let her keep the eggs until she loses interest. For African Greys, the average clutch size is three eggs, but it can be as few as one or as many as five, they usually lay an egg and skip a day until the entire clutch is laid, some hens will sit on the eggs and care for them, some won't. Most vets agree that a healthy hen can lay two clutches a year with no adverse affects to their health. Diet is important while Jeremiah is laying. If she will eat vegetables, I would offer kale, sweet potatoes, carrots, crushed egg shell, sprouts, vitamin rich foods will keep her healthy while she's producing eggs. Keep a close eye on her while she's laying and make sure she continues to eat and exercise.
Continue to care for her as you normally would, when Jeremiah's hormone levels drop back to normal her personality will really start to show. Best of luck to you and your girl.
