Last year I noticed that some clutches started off on frozen thawed without an issue. I then realized that they were clutches that I didn't cut. This year I decided not to cut eggs unless the eggs didn't pip within 48 hours of the first one to pip. So far 5+ clutches have started on frozen thawed which is unheard of. I've gotten approx. 40 babies to start on f/t and haven't had to offer live yet. Maybe there is something to it??
