is it beter to cut open an egg or wait for the snake to pip on its own.

I am wondering if it is better to let the snake open the egg or to open it for them. In this case I have 3 eggs that have piped on there own and one that has not all were laid at the same time so all of them should be ready is there anything that can go wrong if I open the last one or wait it out?

If rest have pipped, go ahead & cut (carefully) the egg.

I cut after the first pip
