Our cockatiel seriously surprised me last night...

[amysaviary]

Yes as many other said do not take the egg also don't think anyone mentioned(but I could have missed it) just because she didnt sit on the egg dosen't mean she would not. They normally do not sit the eggs till the second or even third egg is laid. So it is normal for her to pay no attention to the egg till she would lay 2 or 3 eggs. Also don't take the eggs till she no longer sits on them. If u take them before she is done she may just lay more eggs. So don't think O it has been 21 days I'll take the eggs, go by her time, when she is done then take them. Good luck
