I have 3 baby budgies. Two of them are 4 weeks old and one is 3 weeks old. The oldest 2 have just started to come out of the nest box but they spend all day going in and out of it and they go back in at night. Is it normal for them to keep going back in until they are ready to stay out for good. And I also wanted to know around how long is it between when they start coming out of the box until they are completely weaned?
