Cockatiel Babies

Question
Hello, I would please like to know is it normal for cockatiels to both come out of the nest together and leave the baby birds alone in the nest and every now and then one of them go in the nest for a short while, thanks.

Answer
Yes, once the eggs are hatched, it is okay for both parents to leave the nest for a short while.  This gives you a great time to check on the babies, too!  I used to often put a thin piece of wood across the nestbox hole and take the babies out and cuddle and check on them, then clean out the nestbox (the fecal matter can build up very quickly).
