I did not vote simply because I don't fit in either category.
I cut but it has nothing to do with impatience or needing to know, because if it was the case I could cut way earlier then I do, I just cut because a few years back I saw some hatchlings that had drowned due to their inability to make their way out on their own.
Is this common? Probably not, but as someone who breeds I put all the chances on my side, which is why I also incubate artificially rather then using maternal incubation.
Matter of fact I have 3 clutches in the incubator that I just cut yesterday and I just did a VERY small cut and didn't even look. (I always do small cuts and enlarge as they get ready to emerge.
