Apparently out of 32 eggs laid from 5 hens only one egg showed any visible sign of development

I have heard from Al-Wabra Wildlife Preservation (AWWP) that they have had a disappointing season in breeding Spix's Macaws. Apparently out of 32 eggs laid from 5 hens only one egg showed any visible sign of development. That egg hatched and the chick is doing really well.  11 of the 18 pairs appeared to have been re-paired so hopefully they might have a few more hens laying next year. This season's eggs will be analysed to get a better picture of the status of the eggs - whether, for example, there was early embryonic death, whether sperm actually entered the egg and how much. They also hope to get a better idea of the physiological viability of this season's laying pairs. 

On a more optimistic note I have also heard that the three pairs of Hyacinthine Macaws at Loro Parque produced five young. Two are being raised by their parents (one pair) and three are in the baby station.
