The stupid bird had her chicks!

So no more beautiful turquoise eggs - now there is one or two (we cannot see) little black chick(s). The chick we can see have his beak wide open pointing up, and the parents (both!) are bringing food and putting it in their mouth. Sometimes the food runs away, and so they need to bring some more. It's interesting - right now the father is sitting on the nest more than the mother. In the previous two weeks it was only the mother, and we could not see the father.

However... The condition of the nest continues to deteriorate, and we are still worried that it will collapse and fall down. Anybody knows how long does it take for the chicks to fly/be independent?
