Hi ya'll! Just a question, how long can a fertile egg (that's been warm under a hen for 10 days) go without being warm before it dies? My silkie for some weird reason split her best of 8 eggs yesterday into two piles of four eggs? I went back to check, and she was then sitting on all eight of them? Is there a chance they might make it? I am thinking she was off them for about 12 hours? Our temps lowest here are 23 degrees celcious. Any help please! It's my first lot of fertile eggs!
