Do both parent parakeets have to be in the nest when they have eggs?

Both parent parakeets do not have to be present in the nest at all times when they have eggs. Typically, the female will incubate the eggs, while the male may take turns sitting on them or provide food and protection. However, the male's presence can offer additional security and support for the female during this time. It's important for both parents to be involved in caring for the chicks once they hatch.
