Cockatiels babies

Question
Hello I would please like to know why do cockatiels kill there babies and also leave them in the nest alone! thank you.

Answer
Sarah,

There are many reasons why cockatiels may kill or abandon their babies.  Before I answer this however, I would like to know if this has happened to you?  If so, what type of nestbox did you have, what did you put inside the nestbox, and how old were the parents.  Also, were the parents tame or not handleable, and did you open the box often while the parents were with the eggs/babies?

Thank you,

Cindy
