I'm a noob, but my plan is to not cut the eggs unless I have a straggler that hasn't pipped on it's own. I did have a couple clutches this year and cut some of the eggs on the first clutch, mostly out of impatience on day 53. Second clutch was allowed to pip on its own. Although neither way gave me any problems, I was more comfortable letting them come in their own time, so thats what my plan is for the future.
