Most first clutches fail because the parents are still learning. If she lets the eggs cool off at night, they will not develop at all. All you can do is wait and see if she learns to sit day and night. While this clutch may not work out, she may do better next time. When they are done with these eggs, remove the nest box and rest the pair for 6 months. You should do this after each clutch, whether they hatch or not. In the wild, they only nest once a year. In captivity, they will nest year round, but it is too hard on the female’s health to allow this. So you must limit them to 2 clutches per year, with a 6 month rest in between each clutch.
Thank you for asking Lafeber,
