you can hold the eggs in a cool place for a few weeks small end down and turn them a few times a day.. untill you have a foster pair that are ready. Good luck..Some of my pairs are getting out of their breeding life. They are laying egg irregularly, like 2nd egg laying after 10 days or lay just one egg. Those pair are little rare at my country and expensive. I brought them at old age. Now i dont have enough foster pair to hatch them. Thats why i want to do freeze them for time.
Thank you all.
