I have a male and a female budgie, they have a nesting box but the female has pushed up to 9 eggs at once out of her nest, prior to this she pushed out two eggs. The male goes into the nesting box from time to time and they stay in the box together, he will come out for a feed and return to the nest. After pushing out the nine eggs she is back in the nest and been sitting but I can’t see her, she is sitting very low in the nest. Is there anything I can do? I wondered whether she is throwing them out because they maybe unfertilized eggs. Can you please help me cos I’m pretty keen to see some babies!!
