Is it safe to assume it was not fertile? I have 14 eggs that I'm incubating. I'm on day 13 right now. I just cracked open 8 and all that was in them was pure yolk. I have 3 that are developing, and three that I'm 98% sure developed but didn't continue as they don't look like the three that are doing well... I kept them in there anyway, and will peek at them tomorrow night. I'm mostly wondering on the 8 I just cracked open if because they didn't develop at all, does that mean they were not fertile?? These were shipped eggs too. TIA!
