We think we are due for some babies, my daughter has 2 cockatiels, Gemini and Leo. Leo has laid before, but she would only drop the eggs to the bottom of the cage, she would not go into the next box, We had decided to take the nest box away but she is looking quite large again and she has been into the box this time. So needless to say the box stays until we are sure. She is a very loving (on her own terms) and she would make a good mother if she laid the eggs in the right place and did not drop them to the bottom of the cage. Each time she does this she will go looking for the eggs and gets very flustered when she can't find them. Last time she laid, most of them broke as you would expect, but one went through the bars and did not break, bless her she sat over the egg all day, but of course when we realised what had happened it was too late, we moved it up but nothing came of it. Anyway will keep you informed on the progress.
